It's not the smallest, but WARM. I only had one night where I slept in all my clothes, at 5,150 meters. The included pocket is nice for storing small items.\n\n My only complaint is that the hood is a little small - I move around a lot in my sleep and find it is difficult to get a good \"fit\".\n\nThe only time I have felt cold in this bag was winter camping in a car (big metal box) in Lake City, Colorado, with temperatures below 0F.","textLength":729,"csFlag":false,"inappropriateFlag":false,"reviewedFlag":false,"autoModerated":false,"published":true,"incentivized":false,"upVotes":1,"downVotes":0,"orderId":null,"dimensions":[],"responses":[],"tags":[],"media":{"photo":[],"video":[],"audio":[]},"user":{"nickName":"Daniel K.","firstName":null,"lastName":null,"emailAddress":null,"externalId":null,"city":null,"state":null,"country":null,"ageRange":null,"badge":null,"shopperProfiles":[]},"reviewedDate":null,"purchaseDate":null,"dateCreated":"2023-08-11T00:00:00-04:00","customData":[],"incentiveType":null,"campaign":null,"deviceFingerprint":null,"topics":[],"syndication":{"sourceName":"seatosummit.com","siteUrl":"https://seatosummitusa.com/","logoUrl":"https://images.turnto.com/site/syndicationlogos/2109_LH48.png"},"catalogItems":[{"sku":"11306-S2043","title":"Sea To Summit Alpine Down -20 Sleeping Bag","url":"https://www.scheels.com/p/11306-S2043","category":"sleeping-bags","reviewCount":6,"ratingCount":6,"averageRating":5,"ratingBreakdown":{"1":0,"2":0,"3":0,"4":0,"5":6},"active":true,"attributes":[]}]},{"id":4795711,"locale":"en_US","rating":5,"title":"Best Bag","text":"Best bag I own!","textLength":15,"csFlag":false,"inappropriateFlag":false,"reviewedFlag":false,"autoModerated":false,"published":true,"incentivized":false,"upVotes":0,"downVotes":0,"orderId":null,"dimensions":[],"responses":[],"tags":[],"media":{"photo":[],"video":[],"audio":[]},"user":{"nickName":"James G.","firstName":null,"lastName":null,"emailAddress":null,"externalId":null,"city":null,"state":null,"country":null,"ageRange":null,"badge":null,"shopperProfiles":[]},"reviewedDate":null,"purchaseDate":null,"dateCreated":"2022-08-04T00:00:00-04:00","customData":[],"incentiveType":null,"campaign":null,"deviceFingerprint":null,"topics":[],"syndication":{"sourceName":"seatosummit.com","siteUrl":"https://seatosummitusa.com/","logoUrl":"https://images.turnto.com/site/syndicationlogos/2109_LH48.png"},"catalogItems":[{"sku":"11306-S2043","title":"Sea To Summit Alpine Down -20 Sleeping Bag","url":"https://www.scheels.com/p/11306-S2043","category":"sleeping-bags","reviewCount":6,"ratingCount":6,"averageRating":5,"ratingBreakdown":{"1":0,"2":0,"3":0,"4":0,"5":6},"active":true,"attributes":[]}]},{"id":4795710,"locale":"en_US","rating":5,"title":"Great bag, light but warm","text":"Great bag, light but warm","textLength":25,"csFlag":false,"inappropriateFlag":false,"reviewedFlag":false,"autoModerated":false,"published":true,"incentivized":false,"upVotes":0,"downVotes":0,"orderId":null,"dimensions":[],"responses":[],"tags":[],"media":{"photo":[],"video":[],"audio":[]},"user":{"nickName":"Jason A.","firstName":null,"lastName":null,"emailAddress":null,"externalId":null,"city":null,"state":null,"country":null,"ageRange":null,"badge":null,"shopperProfiles":[]},"reviewedDate":null,"purchaseDate":null,"dateCreated":"2021-11-18T00:00:00-05:00","customData":[],"incentiveType":null,"campaign":null,"deviceFingerprint":null,"topics":[],"syndication":{"sourceName":"seatosummit.com","siteUrl":"https://seatosummitusa.com/","logoUrl":"https://images.turnto.com/site/syndicationlogos/2109_LH48.png"},"catalogItems":[{"sku":"11306-S2043","title":"Sea To Summit Alpine Down -20 Sleeping Bag","url":"https://www.scheels.com/p/11306-S2043","category":"sleeping-bags","reviewCount":6,"ratingCount":6,"averageRating":5,"ratingBreakdown":{"1":0,"2":0,"3":0,"4":0,"5":6},"active":true,"attributes":[]}]},{"id":4795713,"locale":"en_US","rating":5,"title":"A dream of a bag!","text":"I already owned the APII and truly loved it before treating myself to the warmer APIII for the extra cold nights when heading up to Northern New Mexico.
