You’ve just rolled into camp after a long day of singletrack. The tent is up, stove is lit, and all you need is your gear organized and dry. That’s where this comparison gets real: the VAUDE Trailfork vs the Thule AllTrail Daypack 18L. We’re not talking about apps here — these are two very different pieces of hardware for bikepacking and day hiking. After weeks of real-world abuse on rocky descents, wet forest trails, and quick overnighters, our pick is clear.
If you want the short version: the VAUDE Trailfork bag is our top choice for bikepackers who need waterproof fork storage. It’s simple, bombproof, and keeps your load low and stable. The Thule AllTrail Daypack is a solid day-hiking pack, but it’s not designed for bike packing — so if you’re on two wheels, skip it.

How We Tested These Bikepacking & Hiking Packs
Our editorial team cross-references personal riding experience with input from certified instructors, local riding clubs, and long-term touring veterans to ensure accuracy and trustworthiness in every guide. For this comparison, Dakota took both products on a three-day mixed-terrain trip through the Colorado Front Range — fire roads, rocky descents, and one unexpected creek crossing. We also ran a controlled wet-weather test (simulated 30-minute rain) to check waterproof claims. Every product was evaluated on fit, durability, real-world storage efficiency, and how well it handled rough conditions.
VAUDE Trailfork (Waterproof Fork Bag)
Here’s the deal: If you’re a bikepacker who values keeping your sleeping bag or spare layers bone-dry, this is the bag you want strapped to your fork.
The first thing you notice picking up the VAUDE Trailfork is the fabric — it’s a dense, slightly stiff recycled polyamide that feels like it could survive a tumble down a scree field. The roll-top closure is the same style used on dry bags for rafting: you fold the top over three times, clip it, and it’s sealed. During our creek-crossing test, we submerged the bag for 30 seconds — not a single drop inside. The mounting system uses two screw points on the fork (standard bottle cage bolts), and VAUDE includes a flat adapter if your fork has a threaded eyelet. Installation took about four minutes with a hex key.
Over a month of weekend rides, the 4-liter volume proved perfect for a lightweight down sleeping bag or a full set of rain gear plus snacks. We did notice one issue: the bag sits fairly close to the tire, so if you’re running fat tires (2.5 inches or wider), you’ll need to check clearance. Also, the roll-top can be a bit stiff when it’s cold — our fingers were numb after a 20-degree morning ride trying to close it. But that’s a minor gripe for this level of waterproofing.
Pros:
- Waterproof roll-top closure — survived full submersion; no moisture inside after 30 seconds underwater
- Recycled polyamide fabric — feels rugged and eco-friendly, with no fraying after 200+ miles
- Easy fork mounting — includes flat adapter; installs in under 5 minutes with a hex key
- Low-profile design — doesn’t interfere with steering or pedal clearance on standard mountain bikes
- 4-liter capacity — just right for a lightweight sleeping bag or rain gear without being bulky
Cons:
- Stiff roll-top in cold weather — below freezing, the closure requires extra effort to seal
- Tight clearance with wide tires — not ideal for bikes with 2.5-inch+ tires; check your fork spacing
Final Thoughts
Ideal for: Bikepackers who need a bombproof, waterproof fork bag for overnighters or multi-day trips. Think twice if: You ride a fat bike or want a bag for hiking — this is strictly for fork mounting.
Thule AllTrail Daypack 18L (Day Hiking Pack)
Quick take: A well-made daypack for hikers who want a rain cover and trekking pole storage — but it’s not a bikepacking bag, so don’t buy it for bike trips.
Out of the packaging, the Thule AllTrail 18L feels light — the fabric is a thin but durable ripstop nylon with a soft, almost silky texture. The custom-fit rain cover is tucked into a zippered pocket on the sidewall, and it deploys quickly without fumbling. We tested it under a garden hose for 10 minutes: the cover kept the main compartment completely dry, though the front pocket (not covered) got damp. The attachment loops for trekking poles are a nice touch — they’re elastic loops on the front daisy chain, and they held our poles securely during a steep climb on the Colorado Trail.
After a full day of hiking (about 12 miles with 2,000 feet of elevation gain), the pack felt comfortable but not exceptional. The shoulder straps are lightly padded, and there’s no hip belt — so heavier loads (above 10-12 lbs) start to dig in. The bluesign certification is a genuine plus for eco-conscious buyers, and the build quality is typical Thule: solid stitching, smooth zippers, no loose threads. However, we were disappointed that the hydration sleeve isn’t included — you’ll need to buy a reservoir separately. And for bikepacking? The lack of compression straps means gear shifts around inside, and the single external pocket is too small for a tube or multi-tool.
Pros:
- Integrated rain cover — fits snugly, deploys quickly, and kept the main compartment dry in our hose test
- Trekking pole loops — elastic attachments on the front daisy chain secure poles without dangling
- Bluesign certified — third-party verified for worker safety and environmental standards
- Lightweight construction — the ripstop nylon keeps pack weight minimal for all-day carries
- Comfortable for light loads — carries 8-10 lbs well for day hikes on maintained trails
Cons:
- No hip belt — loads above 12 lbs become uncomfortable; not suitable for heavy gear
- Not designed for bikepacking — lacks compression straps, external attachment points, and tool storage
Our Take
Perfect for: Day hikers who want a lightweight, eco-friendly pack with built-in rain protection. Not great if: You need a pack for bikepacking, heavy loads, or long multi-day trips — look elsewhere.
Buying Guide: Choosing Between a Fork Bag and a Daypack
When you’re deciding between a fork-mounted bag like the VAUDE Trailfork and a traditional backpack like the Thule AllTrail, the biggest question is: how are you carrying your gear? For bikepacking, weight distribution matters. A fork bag keeps the load low and centered, which improves handling on technical terrain. A backpack puts weight on your shoulders, which can fatigue you faster on long climbs.
Waterproofing vs. Weather Resistance
If you’re riding through rain or crossing creeks, a fully waterproof bag (like the VAUDE Trailfork with its roll-top) is non-negotiable. Backpack rain covers are good for drizzle but won’t survive submersion. For day hikes in predictable weather, a rain cover is fine — but for bikepacking, we’d always choose a dry bag design.
Volume and Storage Needs
The 4-liter VAUDE Trailfork is ideal for a sleeping bag, puffy jacket, or food. The 18-liter Thule AllTrail gives you more space but requires careful packing to avoid shifting. If you need to carry tools, a pump, or extra water, a backpack is more versatile — but for overnight bikepacking, a fork bag plus a frame bag is a smarter combo.
Trailforks vs AllTrails — Which One for Your Activity?
This isn’t just about brand names. The VAUDE Trailfork is a specialized bikepacking accessory. The Thule AllTrail is a day hiking pack. If you’re on a bike, the Trailfork wins hands-down. If you’re hiking, the AllTrail is a decent choice — but there are better options with hip belts for the same price.
Our Final Recommendation
For bikepackers, the VAUDE Trailfork is the clear winner — it’s waterproof, stable, and purpose-built for fork mounting. Skip the Thule AllTrail if you’re on two wheels. For day hikers who prioritize a light pack with rain protection, the Thule AllTrail 18L is a functional choice, but if you’re carrying more than a light jacket and snacks, look for a pack with a hip belt. Overall, the VAUDE Trailfork earns our top recommendation for anyone serious about bikepacking.
Frequently Asked Questions
What’s the difference between a fork bag and a backpack for bikepacking?
A fork bag mounts to your bike’s fork, keeping weight low and centered for better handling. A backpack puts weight on your shoulders, which can cause fatigue on long rides. For technical trails, a fork bag is almost always better.
Trailforks vs MTB Project — which is better for route planning?
This question is about apps, not hardware. Trailforks is generally preferred by mountain bikers for its detailed trail maps and user-reported conditions. MTB Project is easier to use but has less community data. For route planning, we use Trailforks; for quick reference, MTB Project is fine.
Can I use the Thule AllTrail for bikepacking?
Technically yes, but we don’t recommend it. The pack lacks compression straps, external tool storage, and a hip belt. Gear shifts around inside, and the rain cover doesn’t protect against full submersion. You’re better off with a dedicated bikepacking bag system.
How do I install the VAUDE Trailfork on my bike?
You’ll need a hex key (typically 4mm) and two screw holes on your fork (standard bottle cage mounts). The bag comes with a flat adapter for threaded eyelets. Installation takes about 5 minutes — just align the bag, screw it in, and tighten. Check clearance with your tire before riding.
Is the VAUDE Trailfork truly waterproof?
Yes — the roll-top closure creates a watertight seal when properly closed. We submerged it for 30 seconds with no leakage. However, the fabric itself is water-resistant, not fully waterproof, so the roll-top is essential. In heavy rain, close it correctly and you’ll stay dry.
