One Planet Nitrous

This is the lightest bag for its warmth rating on the market: at approx 535 grams, the -1°C version in the regular is unbeatable. We’ve used technical know-how and quality materials to keep it warm and practical as well as super light: we’ve used 3D, vertical V-baffles filled with 800+ loft DWR down; a full zip allows venting while the box foot prevents cold spots; and there’s a draft tube, three-quarter hood and internal chest drawcord.

The Nitrous is also versatile. It’s available in three warmth ratings and three sizes, each compatible with the Quest to further extend the options. (The Quest attaches inside the bag easily and securely on either side of the zip.) Other features include Vapour Vent fabric with a water-repellent coating and a zip protector on the YKK zip.
