Product Description
Long runs and race days call for a bottle, a phone, keys, and several gels, and all of it needs to stay put once the pace picks up. Nerd Belt has perfected the no-bounce belt and pack system, offering storage, fueling, and access all without limiting performance.
NBreverse is the first Nerd Belt made to be worn around your back with, so your bottle and fuel ride comfortably behind you while you knock off the miles.
Hydration you can reach on the move – Squeeze the pouch to slide the bottle in or out without stopping. It takes the included 550 ml bottle or a 750 ml bottle, so you can carry the fluid a long run calls for.
Fuel and essentials in their own spots – A phone compartment, room for four to six gels, and a hook for your keys let you find what you need without digging. It suits a half marathon, marathon, Ironman 70.3, full-distance Ironman, or ultra.
A belt designed to sit still – The strap adjusts to your waist, and Nerd Belt designed the NBreverse to sit securely on the small of your back without bouncing at any pace. Two sizes cover waists from 25 to 41 inches.
