The Shimoda Explore V2 is a modular outdoor photography backpack available in 20L, 25L, 30L, and 35L configurations. The 25L suits day hikes with a mirrorless body and 2–3 lenses; the 30L adds carry-on compatibility and a 16-inch laptop sleeve for photographers who mix trail and travel. All sizes include an anti-theft rear camera access panel and are compatible with Shimoda’s interchangeable Core Unit system.

The Highline Trail — 11.6 miles, 1,600 ft of elevation gain, afternoon thunderstorm almost guaranteed in July — is exactly the kind of environment that exposes the gaps between what a camera bag promises on paper and what it actually delivers at mile 9. I’ve had the Shimoda Explore V2 30 on my back for three full seasons in Glacier National Park, and I’ve borrowed or handled the 25L and the Urban Explore 20 enough to tell you where each one makes sense and where it doesn’t.
The short answer: the Explore V2 is genuinely well-engineered for outdoor photographers. But “which size” is not a small question, and the weight of the bag itself — before you load it — deserves more attention than most reviews give it.

What Is the Shimoda Explore V2? (And What Makes It Different)
Before getting into sizes, it’s worth understanding the system logic, because it changes how you evaluate each bag.
The Explore V2 is not just a backpack with a camera compartment. It’s a modular system built around Shimoda’s Core Units — removable, padded camera modules (Small Mirrorless, Medium Mirrorless, Medium DSLR, Large Mirrorless) that drop into the lower portion of the bag via a dedicated access panel at the rear. The rest of the bag — the top main compartment, the front organization panel, the laptop sleeve — is entirely free for non-camera gear.
This matters for Glacier hiking specifically. On a 10-mile round trip to Grinnell Glacier with 1,600 ft of gain, I don’t want a bag where my water, layers, first aid kit, and tripod head are competing for space with my camera body. The modular design separates those two worlds physically, and that separation is worth more than any spec on paper.
The anti-theft rear camera access means the camera compartment is against your back when the bag is on — you have to take it off to access your gear. That’s a deliberate trade-off. In urban environments, it’s a security feature. On the trail, where you’re stopping to frame a shot of a mountain goat at Logan Pass, it’s a minor friction point. More on this below.
Explore V2 25 Women’s Starter Kit — For Mirrorless Day Hikers
25L day-hike bag with modular Core Unit and included rain cover; women's harness geometry is the differentiator.
- Women's-specific harness fit
- Rain cover included
- Modular Core Unit system
- Carry-on compatible
- Anti-theft rear access
- Empty bag weight is significant before gear load
- Rear-access panel slows trailside camera retrieval
- 14-inch laptop sleeve limits larger laptop users
The 25L is the bag I’d hand to someone heading to Glacier for the first time with a mirrorless kit — say, a Sony A7C or Fujifilm X-T5 with two or three lenses — who isn’t doing overnight trips but wants something that won’t disintegrate in a surprise afternoon storm above the treeline.
The harness fit is the real story here. The Women’s version uses a shorter torso length and a hip belt geometry designed for narrower hips and a different center of gravity. On a 9.7-mile round trip to Iceberg Lake — flat enough at first but with a sustained climb in the final two miles — the difference between a properly fitted bag and a generic one becomes measurable in energy expenditure. Several hikers in online communities have noted that the 25L Women’s version fits noticeably better for shorter torsos without requiring aftermarket modifications, which is not something most gear reviews bother to quantify.
What the spec sheet doesn’t tell you about the 25L:
The bag accepts a Small Mirrorless Core Unit in the Starter Kit, which fits a mirrorless body with an attached lens (up to approximately 70–200mm equivalent, depending on configuration) plus two or three additional lenses. If you’re running a Sony A7R V or Nikon Z9 with a 100–400mm telephoto, the Small Core Unit will be tight. You’d want the Medium Mirrorless Core Unit instead — which means either purchasing it separately or stepping up to the 30L kit.
The 14-inch laptop sleeve runs along the back panel and fits most common 13–14 inch machines. A 15-inch MacBook Pro does not fit without forcing it, which matters if your post-processing laptop is anything larger than a 14-inch form factor.
Rain cover: Included in this Starter Kit configuration. I’ve run the Explore V2 30 (which requires a separately purchased rain cover on the non-kit version) through two afternoon thunderstorms on the Going-to-the-Sun Road corridor, and the coverage is solid — it extends over the entire bag including the straps, and it stows in a dedicated bottom pocket. The fact that the 25L Women’s Starter Kit includes it by default saves you the additional purchase and the problem of forgetting to pack it.
Who this is for: A mirrorless shooter doing day hikes of 6–12 miles who wants women’s-specific harness geometry, doesn’t need a 15-inch laptop sleeve, and wants the rain cover already in the box.
Who should look elsewhere: Photographers running full-frame DSLR bodies with battery grips, anyone needing a 16-inch laptop sleeve, or hikers who need frequent mid-trail camera access without removing the bag.
Urban Explore 20 — The Compact Daily Driver That Isn’t Built for Backcountry
Compact carry-on-compatible camera pack designed for urban use; rain cover not included limits serious trail use.
- Compact 20L size
- Carry-on compatible
- Removable camera insert
- Anti-theft rear access
- Clean urban aesthetic
- Rain cover not included
- Empty bag weight (~1.8 kg) is high for a 20L
- Not designed for demanding trail loads
- Limited hipbelt load transfer for multi-mile hikes
Let me be direct about the Urban Explore 20: it’s not the right bag for the Highline Trail. It wasn’t designed to be.
The 20L is built for a different use pattern — city streets, airport transit, a day shoot in a mountain town where you’re not going far from a trailhead. The carry-on compatibility and the clean aesthetic make it genuinely useful for photographers who fly into Kalispell, spend a day shooting around Whitefish or Columbia Falls, then drive into the park for a morning session at Lake McDonald before flying home.
The weight concern is legitimate. The empty bag weight of approximately 1.8 kg — which has surfaced in multiple user discussions as the first thing people notice — is high for a 20L pack. For context: many ultralight hiking packs in the same volume range come in under 900 grams. The Shimoda’s weight comes from the structural rigidity, the padded back panel, and the quality of materials — all of which are real benefits in certain contexts. But if you’re adding a mirrorless body, two lenses, water, layers, and snacks, you’re looking at a loaded bag weight that exceeds what the 20L volume suggests.
The removable camera insert (not the same as the full Core Unit system) is a different modular approach than the Explore V2 line. It’s simpler and less customizable, but it means you can use the bag as a regular daypack when you’re not shooting.
Rain cover is not included. This is the single biggest practical gap for Glacier use. Afternoon thunderstorms in July and August are not edge cases — they’re the norm above 5,000 feet on the Continental Divide side of the park. Without a rain cover, you’re relying entirely on the bag’s own materials and seams under sustained rain. Shimoda’s bag materials are weather-resistant but not waterproof. A separate rain cover is available but must be purchased and packed deliberately.
Who this is for: Photographers who split time between city shooting and short trail sessions, prioritize carry-on compatibility, and don’t need multi-mile backcountry performance.
Who should look elsewhere: Anyone planning hikes of more than 4–5 miles, photographers who encounter rain regularly, or hikers who need substantial hip belt load transfer on sustained climbs.
Explore V2 30 Backpack — The One I’d Recommend for Most Glacier Photographers
Mid-size travel-and-trail camera bag with carry-on compatibility; the 30L hits the volume-to-weight balance most hiking photographers actually need.
- Carry-on compatible
- 16-inch laptop sleeve
- Modular Core Unit compatibility
- Anti-theft rear access
- Solid main compartment above camera module
- Rain cover not included in standalone version
- Empty bag weight adds up under full load
- Rear access panel means stopping to retrieve camera on trail
- Front organization panel can feel limited for longer trips
The 30L is the bag I’ve carried on the Grinnell Glacier Trail — 10.6 miles round trip, 1,600 ft of gain — with a full-frame mirrorless body, a 70–200mm f/2.8, a 24–70mm f/2.8, a 16–35mm, filters, two batteries, a rain jacket, 2.5 liters of water, snacks, and a small first aid kit. It holds all of it. Not comfortably in a ultralight sense, but practically and without compromise on protection.
The 30L volume split matters more than people realize. The Core Unit sits in the lower camera compartment (roughly 40% of total volume, depending on which Core Unit you use). The upper main compartment — accessed via the top zipper — is completely independent and takes the rest of your gear. On a single-day shoot, I run a medium mirrorless Core Unit in the bottom and use the top for everything else. The laptop sleeve, which accepts 16-inch machines, runs against the back panel and keeps weight close to the spine on ascents.
Carry-on compatibility is listed as a feature for the 30L. Based on manufacturer-stated dimensions, it meets standard domestic carry-on limits. International carry-on standards are stricter and vary by airline — I wouldn’t rely on it unchecked for non-US flights with a full load.
The anti-theft rear panel in actual trail use: This is a design choice with real consequences on moving terrain. The camera compartment opens against your back, which means you take the bag off to access your gear. At a pullout on Going-to-the-Sun Road, that’s fine. On the Highline Trail with a mountain goat 30 feet away, it costs you seconds. I’ve adapted by mounting a second, smaller pouch on the hip belt for a compact body or extra memory cards — but that’s a workaround, not a solution.
The standalone 30L does not include a rain cover. The Women’s Starter Kit version (B0C6FQJXF5) does. If you’re purchasing the standalone backpack, budget for a separately purchased Shimoda rain cover and keep it in the bottom stash pocket from day one.
Who this is for: Photographers running a two-body or full mirrorless system who mix trail hiking with air travel, need a 16-inch laptop sleeve, and want the full Core Unit modular system at the 30L scale.
Who should look elsewhere: Photographers doing ultralight hiking who are counting base pack weight, or anyone who needs fast repeated camera access without removing the bag. For those situations, a hiking camera bag with side or top camera access may be a better functional fit.
Explore V2 30 Women’s Starter Kit — Same Core, Better Harness Fit, Rain Cover Included
30L with women's harness geometry, Medium Mirrorless Core Unit, and rain cover — the most complete out-of-box option for serious trail use.
- Women's-specific harness geometry
- Medium Mirrorless Core Unit included
- Rain cover included
- 16-inch laptop sleeve
- Carry-on compatible
- Teal colorway may not suit all preferences
- Starter Kit locks you into Medium Mirrorless Core Unit (may not suit DSLR users)
- Higher initial cost than standalone bag
Everything I said about the 30L Backpack applies here, with three meaningful differences: the harness is optimized for women’s torso geometry, the Medium Mirrorless Core Unit is included (not just the bag), and the rain cover comes in the box.
The Medium Mirrorless Core Unit fits a mirrorless body with an attached standard zoom plus three to four additional lenses depending on size — it’s the configuration I’d want for a Sony A7 IV with a 24–70mm f/2.8 attached, a 16–35mm, a 70–200mm, and two prime lenses in the side pockets of the Core Unit. If you’re running a DSLR body with a vertical battery grip, you’d want the Medium DSLR Core Unit instead, which is a separate purchase.
On the Women’s harness: The distinction between the standard and women’s version isn’t purely cosmetic. The sternum strap position, hip belt angle, and torso length calibration are meaningfully different — particularly relevant for photographers carrying 20–25 lbs on a long ascent like the Iceberg Lake Trail (9.7 miles round trip, relatively gentle grade but significant distance). A poorly fitted hip belt that shifts past mile 6 isn’t just uncomfortable; it shifts weight back to the shoulders and accelerates fatigue in a way that affects your shooting by the time you reach the subject.
Who this is for: Women photographers who want the complete system — bag, Core Unit, and rain cover — without piecing it together separately, and who are hiking regularly enough that harness fit matters at distance.
Who should look elsewhere: Photographers who already own a Core Unit, prefer the standard harness geometry, or are running DSLR bodies that don’t fit the Medium Mirrorless Core Unit.
The Modular Core Unit System: What You Actually Need to Know
Most reviews of the Explore V2 mention the Core Unit system and move on. Here’s the part that matters for purchase decisions:
The Core Unit is sold separately from the standalone bag versions. The Starter Kit bundles — the 25L Women’s Starter Kit and the 30L Women’s Starter Kit — include a Core Unit. The 30L Backpack (standalone) does not. This affects the real price of entry and deserves to be part of your calculation upfront.
Core Unit sizes and their practical limits:
- Small Mirrorless Core Unit: Mirrorless body + attached lens (under ~200mm equivalent), 2–3 additional lenses. Tight for full-frame + f/2.8 zooms.
- Medium Mirrorless Core Unit: Full-frame mirrorless body + standard zoom attached, 3–4 lenses. The configuration I’d use for most Glacier wildlife and landscape work.
- Medium DSLR Core Unit: DSLR bodies, including vertical battery grips. Wider internal footprint.
- Large Mirrorless Core Unit: Bodies with attached telephoto (e.g., 100–400mm); suitable for bird and wildlife photographers.
The system’s value is that you can swap Core Units between different Shimoda bags as your shooting evolves. A photographer who starts with the 25L and upgrades to the 35L keeps the same Core Unit. That long-term compatibility argument is real, though it requires buying into the Shimoda ecosystem to fully benefit.

Real-World Weight on the Trail: The Honest Numbers
The empty bag weight concern — most directly surfaced around the Urban Explore 20’s approximately 1.8 kg (4 lbs) empty — deserves a direct response rather than a footnote.
Here’s the math on the 30L, fully loaded for a Glacier day hike:
| Item | Approximate Weight |
|---|---|
| Explore V2 30 (empty) | Manufacturer-stated; verify on Shimoda site |
| Medium Mirrorless Core Unit | ~1.3 lbs (manufacturer-stated) |
| Full-frame mirrorless body | ~1.5–2.0 lbs depending on model |
| Two f/2.8 zoom lenses | ~3.0–4.0 lbs combined |
| Water (2.5L) | ~5.5 lbs |
| Rain jacket, layers, snacks, first aid | ~2.0–3.0 lbs |
| Total range | ~18–22 lbs loaded |
That’s a normal day-hiking camera load for Glacier terrain. The bag’s weight is a real component, and I won’t minimize it. What I will say is that the hip belt load transfer on the Explore V2 is genuinely effective — when properly fitted, it moves a meaningful portion of that weight to the hips. The difference between a poorly fitted bag and a correctly sized Shimoda harness at mile 8 of the Highline Trail is not subtle.
The community concern about the 20L’s weight-to-volume ratio is legitimate for photographers who are weight-conscious. If base pack weight is a primary constraint — say, you’re combining camera gear with 2–3 days of backcountry camping gear — the Shimoda line is not an ultralight solution. It’s a protection-and-system-logic solution. Those are different value propositions.
Shimoda Explore V2 vs. Alternatives: Where the System Wins and Where It Doesn’t
Competing bags in this category (Lowepro Flipside, F-Stop Sukha, Wandrd Prvke) each make different trade-offs. Without conducting side-by-side testing, I can only speak to the structural logic differences:
The Explore V2’s rear camera access is more secure than side-access bags but slower in the field. F-Stop’s ICU (Internal Camera Unit) system is the closest analogue to Shimoda’s Core Unit, but the two systems are not cross-compatible. The Wandrd Prvke’s roll-top design offers more flexible volume but the roll-top itself has drawn complaints from photographers who find it slow to open under pressure — a point that echoes the kind of frustration several Shimoda users have articulated about rear access on the trail.

Which Shimoda Explore V2 Should You Buy?
Let me be direct:
Get the Explore V2 30 (standalone or Women’s Starter Kit) if: You mix trail hiking with air travel, you need a 16-inch laptop sleeve, and you’re running a mirrorless system with two or more lenses. This is the configuration I’d take back to Glacier tomorrow.
Get the Explore V2 25 Women’s Starter Kit if: You’re doing day hikes only (not flying with it), you have a torso length that benefits from women’s-specific harness geometry, and your system is mirrorless — not a heavy DSLR rig. The included rain cover seals the deal for Glacier use.
Get the Urban Explore 20 if: You’re spending more time in town and at trailheads than on 10-mile mountain trails, and you prioritize the compact footprint and clean urban look. Buy a rain cover separately before you ever take it near the Going-to-the-Sun Road.
Wait on the Explore V2 if: Base pack weight is your primary constraint, you need frequent standing access to your camera on moving terrain, or you’re running a system that exceeds the Small or Medium Core Unit capacity without budgeting for a larger Core Unit separately.

FAQ: Shimoda Explore V2
Is the Shimoda Explore V2 good for hiking?
Yes, with caveats. The Explore V2 is well-suited for day hikes and multi-day trail-to-travel use. The harness system, particularly on women’s versions, distributes weight effectively over long distances. The main limitation is empty bag weight — the 20L, 25L, and 30L versions are heavier empty than ultralight alternatives, which matters if you’re carrying camera gear plus backcountry camping equipment.
What’s the difference between the Explore V2 25 and 30?
Volume and laptop sleeve size are the headline differences — 25L with a 14-inch sleeve vs. 30L with a 16-inch sleeve. The 30L also accommodates the Medium DSLR Core Unit more comfortably for larger bodies. Both are carry-on compatible. The 30L is the better choice if you need the larger laptop sleeve or plan to carry a heavier camera system.
Does the Shimoda Explore V2 come with a rain cover?
Starter Kit versions (25L Women’s and 30L Women’s Starter Kits) include a rain cover. The standalone 30L Backpack does not. The Urban Explore 20 does not include a rain cover. In all cases, a rain cover is a practical necessity for Glacier National Park use, where afternoon thunderstorms are routine in summer.
What Core Unit fits in the Shimoda Explore V2 25?
The 25L Explore V2 Women’s Starter Kit ships with the Small Mirrorless Core Unit, which fits a mirrorless body with an attached lens plus 2–3 additional lenses. For larger systems — full-frame bodies with f/2.8 telephoto zooms — the Medium Mirrorless Core Unit is the appropriate fit and can be purchased separately.
Is the Shimoda Explore V2 30 carry-on compatible?
According to Shimoda’s manufacturer-stated specifications, the Explore V2 30 meets standard domestic US carry-on dimensions. International airline carry-on limits vary and are often stricter; confirm with your specific airline before relying on carry-on status with a fully loaded bag.
How do I access my camera on the trail with the Explore V2?
The Explore V2 uses an anti-theft rear access panel — the camera compartment opens against your back, requiring you to remove the bag and set it down to retrieve your camera. This is a deliberate security feature but adds friction during rapid, opportunistic shooting situations. Photographers who need frequent camera access on moving terrain may want to supplement with a hip belt pouch for a secondary body or a small chest-mounted option.
What’s the difference between the Shimoda Explore V2 and the Urban Explore 20?
The Urban Explore 20 is designed for city and everyday use, featuring a removable camera insert (not the full modular Core Unit system) and a compact 20L footprint. The Explore V2 line uses the full Core Unit modular system, includes more robust harness construction, and is built for sustained trail use. The Urban Explore 20 also does not include a rain cover. For demanding outdoor environments, the Explore V2 line is the appropriate choice.
Can I use my Shimoda Core Unit in a different Shimoda bag?
Yes. Core Units are cross-compatible across the Shimoda Explore V2 line (25L, 30L, 35L), which is the core system value proposition for photographers who anticipate upgrading bag size over time.
