This is one of the lightest bags for its warmth rating on the market: at just 512 grams, the +2°C version is unbeatable. 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. Other features include super light, downproof by construction and breathable 10 denier Vapour Vent fabric and a zip protector on the YKK zip.

One Planet sleeping bags are rated using the international standard for sleeping bag performance, ISO 23537-1. (This is a revised version of European Standard EN 13537.) This means every sleeping bag has two ‘real world’ and one extreme rating. To determine what temperature might be most suitable for you see our technical pages.
Ethically sourced down
Our down is ethically sourced, harvested and cleaned before purchase, with both the down and our supplier passing independent International Down and Feather Laboratory (IDFL) audits relating to ethical traceability. This means that the white down and feathers we purchase are from animals that haven’t been live plucked or force-fed at any point during the supply chain.
I love this bag !!! I have the regular size which when zipped, is snug (but not uncomfortable) for my 187cm / 112kg frame. Unzipped its like a quilt with a sewn footbox with plenty blanket/bag/material to keep you covered. It packs down small, weighs about 500g but if +2 is not warm enough grab a thermal liner or buy the -1 or -3 model, I don't think you'll be disappointed.
