About NBreverse
The NBreverse comes with a 650ml hydration bottle and is compatible with bottles from 550ml to 750ml. Simply squeeze the pouch to insert or remove your bottle while moving, making it easy to stay hydrated during long training sessions and races.
Multiple compartments provide space for your phone, four to six energy gels and other small essentials, while a separate phone compartment and built-in key hook keep everything organised and secure. The adjustable strap is available in two sizes, helping you achieve a close, comfortable fit with no unwanted movement.
Made from 100% polyester, the NBreverse is suitable for everything from everyday runs to half marathons, marathons, triathlons and ultra events. The included bottle is BPA-free, recyclable and safe for both the dishwasher and freezer.
How does it work
The NBreverse positions the bottle and storage compartments against your lower back, helping to distribute the weight securely around your waist. Its adjustable strap creates a close fit to reduce bouncing and movement, even when running at a faster pace.
The angled bottle pouch can be squeezed to make inserting and removing your bottle easier while moving. Separate storage areas keep your phone, gels and smaller valuables organised, while the key hook prevents your keys from moving around or getting lost inside the belt.
