More riders are using smaller hydration packs, but they still want the convenience of carrying items in a secure, balanced location. That's why Race Face developed the Stash Tank. It's designed with a Lycra and mesh fabric to keep you cool and dry on the trail, plus features a hydration pocket for a 50oz reservoir and the STASH back pocket system to accommodate extra gear, like tools, spare tube, pump, nutrition, and more. Integrated channel over the shoulder helps secure the reservoir tube for easy access. Flatlock seams throughout ensure a chafe-free experience. You'll never need to wear a traditional pocketed XC jersey again.
