The UltrAspire Proton is a new take on the 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. The padded, breathable mesh back panel 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.

Customer feedback

Comments: I love the magnetic pocket feature to keep electrolyte capsules in and dry.  Used this in a really hot marathon and it was perfect!  Love that the water bottles are not round!
