About NB600 Groove

The belt includes two ergonomically shaped 300ml Groove bottles, providing 600ml of hydration in total. Each bottle is shaped to contour naturally around your hips, helping the belt sit smoothly against your body while you run.

Alongside the bottles, the NB600 Groove offers space for your energy gels, phone and keys, plus a convenient way to carry your race bib. This makes it a practical choice for longer training sessions and races where you need easy access to hydration and fuel.

Suitable for all distances and paces, the NB600 Groove can be used for everything from everyday runs and half marathons to marathons, Ironman events and ultras. The neoprene belt can be hand washed, while the BPA-free bottles are dishwasher and freezer safe.

How does it work

The NB600 Groove uses a stretchy, adjustable strap to create a secure fit around the hips. This helps limit unwanted movement and bouncing as you run, while the lightweight neoprene construction sits comfortably against the body.

Its two 300ml bottles feature an ergonomic grooved shape that follows the natural contours of your hips. The balanced bottle positioning distributes the weight around the belt, giving you quick access to hydration while leaving room for gels, valuables and your race bib.

About nerd belt

nerd belt was created by professional triathlete and multiple-time IRONMAN champion Steve McKenna, who wanted a better way to carry hydration and fuel while running. Designed to perform at any pace with zero bounce, each belt comfortably carries 400–600ml of fluid alongside essentials such as a phone, gels and bars.

What began as a single belt made for Steve’s own training quickly grew into Australia’s number one-selling hydration belt. Today, nerd belt continues to help runners and endurance athletes stay fuelled, hydrated and comfortable throughout training and racing.
