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

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

Marmot Aspen 40 Ultralight

rated 2.5 of 5 stars The bag is rated at 40 degrees, works pretty good to that temp. It's very lightweight at 1.5 lbs. It's a good summer bag! I bought this bag last summer and used it in warmer nights than its specified 40 degree temp, so used it as a quilt just laid over me at night. It's very lightweight at 1 1/2 lbs and stuffs into a compression stuff sack. It's filled with Polarguard and compresses very well to the size of a soccer ball, so takes up very little room in my backpack or bike panniers. It's a very… Full review

Big Agnes Horse Thief SL 35°

rated 4 of 5 stars A lightweight hoodless option that lightens the load in your summer pack. Recommended for weather where the temps hover around or above 50°F. Warmth: The bag is rated at 35°F. The bag does a fine job in temperatures above 50°F. Mid 40's and below, the comfort level starts to drop off quick. In temperate climates, like the one here in Minnesota, you can judge the weather well enough to make a pretty good estimate of whether you'll be in comfort range.  Fit and Comfort: I must say, the bag is… Full review
