Design and Build Quality
Rugged Materials, Refined Construction
The 6L Saddle Pack is constructed from Dimension-Polyant VX21—a four-layer laminated fabric originally developed for marine sails—and 420D nylon for abrasion resistance. The result is a bag that’s lightweight, waterproof, and tough enough for technical singletrack.
- Welded seams eliminate stitch holes and enhance waterproofing
- Hypalon reinforcements at contact points prevent wear
- Roll-top closure allows variable volume and compression
- Reflective graphics improve visibility in low light
The bag’s shape is tapered to reduce sway and maximise clearance, especially important for full-suspension bikes and dropper posts.
Mounting System and Stability
Rock-Solid Fit on Rough Terrain
The Apidura Backcountry Saddle Pack uses a three-point attachment system:
- Two seat rail straps with Hypalon-reinforced webbing
- One seatpost strap (or dropper adapter)
- Internal stiffener to maintain shape and reduce bounce
This setup keeps the bag secure and sway-free, even on technical descents and rooty climbs. The optional Dropper Post Adapter (sold separately) allows the bag to sit higher and avoid tire rub on full-suspension bikes.
- No side-to-side wag when packed correctly
- Minimal sag, even with soft gear like clothing or sleeping bags
- Quick to install and remove—ideal for mixed-use bikes
Storage and Capacity
Compact but Surprisingly Capable
With a 6-litre capacity, this saddle pack is ideal for:
- Clothing layers (jacket, base layers, gloves)
- Compact sleep systems (quilt, bivvy, inflatable mat)
- Food and snacks for 1–2 days
- Toiletries or tools in dry bags
The roll-top closure allows you to compress the load tightly, and the external bungee cord on top is perfect for stashing a windbreaker or wet socks.
Note: If you need more space, Apidura also offers a 10L version, but the 6L strikes a great balance for minimalist overnighters or fast-and-light missions.
Waterproofing and Weather Resistance
Built for British Weather
The Backcountry Saddle Pack is fully waterproof, thanks to:
- Welded seam construction
- VX21 and PU-coated nylon fabrics
- Roll-top closure with secure side buckles
We tested it in persistent rain and muddy trails, and the contents stayed bone dry—even after hours of exposure. It’s one of the few saddle bags we’d trust without a secondary dry bag inside.
Real-World Performance
Trail-Tested on Gravel and Singletrack
Over multiple rides across wet moorland, forest trails, and gravel roads, the 6L Saddle Pack proved:
- Stable: No sway or bounce, even on rough descents
- Quiet: No rattling or flapping
- Low-profile: Doesn’t interfere with pedalling or mounting
- Durable: No signs of abrasion or seam stress after weeks of use
It’s especially well-suited to hardtails, gravel bikes, and full-suspension rigs with limited clearance.
