It's ideal for backpacking but versatile enough for couch surfing. The 650-fill-power down is light and packable.\u003c\/p\u003e\u003cp\u003eTemperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38. \u003cbr\u003e\u003cbr\u003eEach bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average \"cold sleeper\" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average \"warm sleeper\" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.\u003c\/p\u003e","brand":"Big Agnes","offers":[{"title":"Cherry Tomato\/Rooibos Tea \/ Regular - Left Zip","offer_id":50622571610177,"sku":"REI-C035610001","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0749\/5093\/4593\/files\/big-agnes-greystone-0-sleeping-bag-1.jpg?v=1791309005","url":"https:\/\/discountsproduct.com\/products\/big-agnes-greystone-0-sleeping-bag","provider":"Discounts Product Store","version":"1.0","type":"link"}
