Nerd Belt NBreverse

The NBreverse is the ultimate waist belt for runners who refuse to compromise on carrying capacity or comfort. Designed to sit securely on your back, this innovative belt keeps your essentials within reach while eliminating bounce at any pace—whether you're tackling a half marathon, full marathon, Ironman, or ultra distance. Built with multiple compartments, the NBreverse organizes everything you need: a dedicated phone pocket, space for 4–6 energy gels, a key hook, and more. The included 550ml hydration bottle fits snugly in the squeeze-access pouch and can accommodate bottles up to 750ml, so you stay hydrated without the slosh. Available in two adjustable sizes—Small (65–85cm waist) and Medium–Large (75–105cm waist)—the NBreverse adapts to your frame. Perfect for training runs and race day alike, it's the gear that lets you focus on what matters: the run.
