This is the lightest bag for its warmth rating on the market: at just 578 grams, the -3°C version is unbeatable, this thermally-efficient mummy bag is designed for use in summer or shoulder seasons. We’ve used technical know-how and quality materials to keep it warm and practical as well as super light: 3D, vertical V-baffles filled with 800-850 loft Hydrophobic 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 quilts to further extend the options. (The Quest or Quest Zero attach inside the bag easily and securely on either side of the zip.) Other features include super light, downproof by construction and breathable 10 denier Vapour Vent fabric and a zip protector on the YKK zip.
