The Big Agnes Spike Lake 15 Degree Sleeping Bag is a traditional down sleeping bag for getting out into the wilderness. Sleeping in a tent is always an adventure and this bag will keep you warm in the night down to 15°F. On the more traditional side of things, this bag does not have a pad sleeve, but don't forget to bring your sleeping pad along on the trip anyways, otherwise it won't reach its fullest potential. Snuggle in and the 600 fill DownTek® water repellent down will wrap you in heat.

Rated 4 out of 5 by from Happy with the purchase This isn’t a to terribly expensive bag and I have been sleeping in 10 degree nights with just shorts and a sweater on and sometimes I’ll even get a little warm. The only thing I do wish was incorporated into the design is a small zip pouch for my phone or just something to contain whatever I need inside my bag. Great purchase though!

Rated 4 out of 5 by from Pleasantly Surprised! I was fully prepared to be cold and disappointed. My prior bag (by manufacturer K) fluffs up to twice the thickness of the Spike Lake, but constantly let me down when temps got below 30, even though it's rated to 20. The Spike Lake is rated to 15. I ignored what I thought was a lack of fill, and brought it with me this past weekend - temps were supposed to be in the low 20's. I was pleasantly surprised. The low hit 22, and......I was warm. I slept well. I awoke rested. The down filled yoke gently wrapped around my neck, laying over my shoulders, keeping warm air inside the bag. The zipper snagged a few times, but other than that, this bag's a keeper.

Rated 5 out of 5 by from Toasty warm! Bought this for trip to Canyonlands in September. Got chilly at night, colder than usual for this time of year. Had no problem staying warm in this bag.

Rated 4 out of 5 by from Snuggly Bought this for two week-long trips in the Wind River Range of Wyoming and Saguache Range of Colorado where I was doing some volunteer log work on historic buildings with HistoriCorps. Great bag to climb into at the end of a day of work. Definitely hotter than I'm used to but I just unzipped it for a cool breeze.
