The Nano Vest is a trail running backpack by the brand Camelbak, ideal for runners looking for a backpack that is both lightweight and functional. An improved version of its predecessor, the Nano Vest features a lighter and simpler fastening system, reflective details, and a safety whistle, all in a lightweight and breathable 3D Micro Mesh model. This featherweight pack is also designed to keep you hydrated throughout your run, thanks to its two easily accessible Quick Stow™ flasks. You will appreciate the high breathability combined with the ultra-comfortable padding of the Nano Vest, as well as its perfect fit and multiple pockets that allow you to carry your small personal items with you.
