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.

Temp Ratings
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.
Very pleased with the sleeping bag, super light and compact but still warm
Service and delivery were excellent. I've given the sleeping bag a brief test and it seems great. Planning to use it on Routeburn Track, Mt Aspiring National Park, NZ, in mid-Nov. Very pleased to have such a light, quality bag to use.
I bought these for the whole family and they were a hit! Light to carry, packs small and super comfy to sleep in. Would recommend!
Used this for the first time on the Three Tarns Pass trip across the Spenser Mountains. A beautiful wee bag. We were in huts all night, but Downies Hut inland from Murchison was a cool night and the Hut old with plenty of gaps (Shame on DOC). I slept well but another 2 or 3 degrees down and I would have slept but been on the cool side. As a product this is a top bag. I suppose the best reference I can give it is that I am going to buy the next warmer model as well. Very light, very compact, very snuggly. I can only assume that these bags are pure down and not down/feather.
Good
