The updated UltrAspire Proton is a unique running hydration belt design with 2 low-profile, rectangular 16 oz ergonomic bottles in-rear and a simple belt hook system replacing the traditional snap buckle. Sweat proof webbing keeps weight down and more breathable mesh enhances long-distance comfort; an open mesh pouch holds gels or keys and a sweat proof magnetic pocket stores electrolyte capsules. What else? The rear shock cord can stash a shell jacket, warmers or gloves.
