Most vests use multi-layer back panels that trap heat. The NVlite uses a single ultra-thin stretchy mesh layer that maximizes airflow, keeping you cooler and reducing sweat loss on long efforts. Combined with its side and waist elastic tightening system, it delivers a no-bounce fit that most vests simply can't match.

The two front pouches hold the included 500ml soft flasks (1L total fluid). The rear pocket is large enough for a spray jacket, 10 gels, and a snack bar simultaneously. Two front phone pockets fit any size phone, and a small front zip pocket with a key hook rounds out the storage.

Nerd Belt tested the NVlite shirtless on runs over 60 minutes and confirmed zero chafe. The soft stretchy hem on the exterior is specifically designed to be skin-friendly even without a base layer.

The NVlite is built for both. Its no-bounce system handles technical terrain just as well as road — the deeper front flask pouches keep bottles secure on descents, and the vest's locked-in fit means no adjustment stops regardless of the surface.

NVlite is purpose-built for 1–3 hour efforts. It's intentionally lighter and more minimalist than larger vests designed for ultras, prioritizing breathability and a streamlined carry over maximum storage capacity.
