Lightweight packing systems need deeply thought-out solutions and an elegant, simple first aid setup is one of them. Working with medical professionals and emergency-first-responders (who are also mountain bikers), we put together the essential trail kit. A waterproof EPX-400 zip bag sports a high-quality weatherproof #8 YKK Aquaguard zipper -- all of which fits perfectly in the Venture, Lookout, and the Cascadia hip packs. Dimensions are 8" x 4.75".
