Apidura Backcountry Downtube Pack – 1.8L

Out of sight. Out of the way. Built to stay.

The Apidura Backcountry Downtube Pack is a low-profile, waterproof stash point for your spare tube, tools, or even a 1L bottle—perfect for rides where space inside the triangle is tight. It straps securely to your downtube (or similar diameter tube) without the need for mounts or cages, giving you set-and-forget storage for bikepacking, MTB missions, or gravel adventures.

With a 1.8L capacity, it’s a flexible space for long-haul essentials, and the single-motion Velcro system keeps it tight and rattle-free on rough terrain. Built from Apidura’s ultra-tough VX21 + 420D laminated fabrics, this pack is fully waterproof, abrasion-resistant, and made to take a beating—without flinching.
