Made of tough Texapore fabric, the Onyx will withstand the battering from wearing packs on long hikes and day to day wear. It's waterproof and breathable and thanks to the pit zips, you can ventilate and keep cool when you're working up a sweat without removing layer.
Pit zips are one of the best ways to avoid hypothermia - don't let your moisture gather inside your clothing then freeze later.
The Onyx has a zip system so a compatible insulated inner jacket can be zipped in if required.
