The Backcountry Tool Pack fits all the essentials to fix a mid-ride mechanical. There is space for a mountain bike inner tube (or two road ones), a small multi-tool, tire levers, and a CO2 canister. Designed for off-road riding, this lightweight, all-weather Tool Pack is constructed from a four-layer laminated fabric suited for hard outdoor use. That means waterproofing, low stretch, and high abrasion and tear resistance to keep gear dry and secure. Fitting neatly under the saddle, it fastens to the saddle rails with an easy-to-use reinforced velcro strap that loops around and secures the Pack to the bike. Durable Hypalon coats the surface to minimise wear and tear on the Pack, and keeps bike frames in good condition. While the body fabric of this Pack is waterproof, due to the stitching process used to assemble the product, there is the possibility for water to enter through the seams when exposed to sustained rain. We recommend using an internal dry bag for contents that must remain absolutely dry.
