Marmot Always Summer

rated 4 of 5 stars Took this camping on a chilly April night in Utah and it stood up well. I was able to slip a small liner inside as well and it got too warm. This bag kept me incredibly warm and was able to fit a liner in quite easily. However the foot box was smaller than I expected. Not horribly so, but just enough to notice. Getting in and out typically wasn't an issue, however the zipper would get stuck every once in a while. Easy enough to adjust. The bag packs incredibly well and puffs up easily after having… Full review

Sea to Summit Traveller TRI

rated 3.5 of 5 stars This is a cost effective and more than adequate light minimal coverage for a quick summer outing in the woods. It is versatile enough for couch surfing relatives over the holidays. It is just wide enough to cover two cozy campers that are not too big in girth on a not chilly summer outing. Originally bought for couch surfing relatives, but I found it useful as a comforter on a fall evening too. That opened the door to other uses. Took it out for a July 6K ft elevation overnight in Sierra Nevadas… Full review

Sea to Summit Spark SP I

rated 4 of 5 stars This is an ultra-ultralight sleeping bag with a short zip. Use it when you want to save weight and if you are prepared to sacrifice some comfort. I am 189cm (6'2"). This bag (size long) weighs 428g (15.097oz) without the stuff sack. It is the lightest sleeping bag I could find. Warmth:This is different for every person. I would say the temperature rating is OK. I am a very cold sleeper so I can use this bag even when it is around the lower limit of 8°C|46°F. I don't mind being somewhat cold, but… Full review

Western Mountaineering HighLite

rated 4.5 of 5 stars This super-lightweight, amazingly compressible, down sleeping bag rated 35 degrees is my go-to bag for just about all of my backpacking trips. While rated at 35 degrees, I'll take it even if it's supposed to get down to 30, and I'll explain that below. I would not take this bag if conditions predicted temps colder than 30 and/or lots and lots of rain. Otherwise, this is a great bag! Since it's a sleeping bag, let's talk about warmth first. I HATE being cold. I like to sleep warm, and I tend to sleep… Full review

Sierra Designs Men's Backcountry Bed 600 2-Season

rated 4 of 5 stars I'm a believer. Took the leap and bought a Sierra Design Backcountry Bed. Zipper-less, roomy, down warm weather sleeping bag. Great bag for side sleepers and those move around a lot at night like me. I find the bag works best for warmer weather nights (over 40 degrees). Great for base camps, car camping, and shorter backing trips. There are lighter bags but at an increased cost. I would buy a SD Backcountry Bed again. I haven't found a more comfortable down bag yet.  I love not having a zipper. Full review

Marmot Aspen 40 Ultralight

rated 5 of 5 stars Needed to cut down on weight for summer backpacking and this was the answer. Very light, packs down to the size of a grapefruit, and really does the job. I realize that this was a Dick's Sport exclusive, but it still has the Marmot name and built in quality. The stitching is excellent and keeps the down in place. I'm 5'11" and 200 pounds. The bag has plenty of room in the hips and shoulders and a squarer foot box than my 3-season bag. I like to toss and turn, so this was perfect.  The exterior… Full review

Western Mountaineering Everlite 45

rated 5 of 5 stars Great lightweight, adaptable bag. I've used it by itself in warm and muggy summer camping in Northwest Arkansas and in the Black Hills on very cool nights. Love it! I bought this bag in preparation for a week in the Black Hills, South Dakota. It's my first down bag of any weight and I couldn't wait to use it so I snuck away for a weekend in the heat and humidity of Northwest AR. For the first night I really didn't need it till 2-3 a.m. and just used it unzipped as a blanket which it was perfect… Full review

Western Mountaineering HighLite

rated 4.5 of 5 stars I absolutely love my HighLite! I call it my cloud because that is what it feels like you are sleeping in :). I think the temperature rating is accurate — I sleep a little cold so I wear extra socks and clothes to bed but works well for my section hikes on the AT. It's amazingly light and packs down so small in a compression sack. When removed from the compression sack it regains all loft with a few shakes. I got the 5'6" size which works great for a petite woman. The HighLite is well made, in… Full review

MontBell Alpine Burrow Bag Thermal Sheet

rated 2.5 of 5 stars Adds extra warmth to a lightweight sleeping bag to extend its use into colder weather. Very lightweight, but very slim cut won't fit big people, but adds a real 5 to 10 degrees to any sleeping bag depending on your metabolism. The good points first: Like most MB gear it is well made and the design is well thought out. It isn't expensive and it is an excellent idea for those who do not have enough money to buy a warmer sleeping bag and who want to camp in cooler conditions. The short zipper makes… Full review
