Recent Warm Weather (above 35°F) Sleeping Bag Reviews

Big Agnes Horse Thief SL 35°

rated 4.5 of 5 stars Love this thing. I've had this for several years with use along the lakeshore of Pictured Rocks and temps in high 30's. I wish they still made this bag so I could buy it for my kids now that they are backpacking also. To answer a couple of questions that may resolve issues posted up years earlier than this one: The pillow sack goes inside with you, not hanging off the edge. I believe some of the cold feeling people may be getting is from not using an insulated air mattress; I made that mistake also… Full review

Therm-a-Rest Space Cowboy 45F

rated 4 of 5 stars The Space Cowboy is a nicely featured 45˚F/7˚C sleeping bag for those seeking a highly compressible, lightweight synthetic sleeping bag option. This bag is readily stuffed into pack crevices or its supplied stuff sack, taking up less room at lower weight than a number of similarly rated bags (albeit at higher price), while providing mummy bag coziness with a draft tube and draft collar for unseasonably cool nights. In the American South where I live, we’ve had the first few flashes of summer-like… Full review

Big Agnes McKinnis

rated 3.5 of 5 stars The Big Agnes McKinnis is a lightweight, down insulated sleeping bag designed for minimalist trips, bike packing, or any time some extra insulation is needed within your sleep system. Versatile enough to go from your warm weather summer bag to a winter liner, I believe the McKinnis would be an excellent addition to many people's kits. The main point I’d like to see redesigned is the hood shape as it currently doesn’t add much function. WARMTH No temperature rating is given for the McKinnis so… Full review

Ozark Trail Sleeping Bag

rated 0.5 of 5 stars This is the most sh*t sleeping bag I have ever used in my life. There is absolutely no way to fix the damn chain. Ozark Trail, make better sleeping bags! Full review

Sierra Designs Backcountry Bed 700 / 35 Degree

rated 4 of 5 stars Well made, but not for me. I'm up and down numerous times during the night. Received one as a warranty replacement for a failed Zissou 700 and returned for credit the next day. Though it's warm and roomy I found it a chore to get in and out of. I'm up numerous times during the night and in and out is a bothersome challenge. Because the blanket is sewn in at waist level one must slide in the legs to hip level and squiggle down and exiting is the opposite. I couldn't bear it, so I returned it and… Full review

Etowah Outfitters 50 Degree Down Sleeping Bag

rated 3.5 of 5 stars An inexpensive, lightweight, rectangular, summerweight bag that can open up to work as a quilt for two. Too bad it doesn't come in long. I sleep warm. In tents, huts, and European hotels (where bedding usually consists of a bottom sheet and a quilt in a quilt cover—that's all), I have suffered through many a night under a quilt or in a sleeping bag that is too warm, sometimes waking up soaked in sweat while others seem to be perfectly comfortable in the same or even more insulation. My wife, not… Full review

Marmot Pounder

rated 4.5 of 5 stars I'm still using this bag that I bought in 2008 or 2009. It has taken me from freezing temperatures to the 80's in a hammock (I just laid on it to keep the mosquitoes from biting!). It's not meant for extremely cold temperatures, but I use it as part of a sleep system that includes a silk liner and a crinkly emergency bivvy sack. On a freezing cold wet night, I'll use all three. The silk liner gives me another 10-15 degrees of warmth, and the emergency bivvy another 20 degrees of warmth. I've used… Full review

Marmot NanoWave 35

rated 3 of 5 stars Well built. Great for summer nights but not for cold weather. I am a Florida hiker/backpacker. I am one of those people northerners laugh at because I wear winter jackets when the weather reaches 65°F and below. Knowing my blood is thinner and I have my own internal insulation (weighing in at 150 lbs), I was hoping this bag would keep me warm. Although this bag is rated to 35°F, I was cooly uncomfortable at 52°F and below. On all occasions where the weather dipped below 55°, I packed wool pajamas,… Full review

Coleman Bambusa

rated 4.5 of 5 stars It is great for three-season camping and packs down small enough to fit on a bike rack. I bought mine years ago and have camped with it several times. I found it to be great for fitting on my bike pannier rack with my bike packing tent and inflatable mattress. For comfort in extreme cold, I've bought a silk liner to add another season rating, but haven't needed to use it...yet. Full review
