Recent Warm Weather Synthetic Sleeping Bag Reviews

Columbia Reactor 35 Mummy

rated 4 of 5 stars This is a great low-price synthetic bag for summer and early fall hiking. The "Omni-Heat" reflective dots do a great job of capturing body heat while the "Omni-Shield" 30D nylon shell blocks wind. A nearly full-length double zipper allows you to quickly and easily adjust the bag for optimum comfort in varying weather. I originally picked up the Columbia Reactor 35 as a backup bag when the airline lost my pack and we weren't certain we'd be able to intercept it on our way into the woods. In the end,… Full review

High Peak E-Z Pak 1000

rated 4 of 5 stars The High Peak E-Z Pak 1000 is a very good, well built, warm weather sleeping bag if you are big enough to fill it up. The construction quality, price, features, and durability are excellent, but the temperature rating is very optimistic. I recommend this sleeping bag only to the "big and tall" crowd. Words to the wise to start; First of all... ALWAYS use a sleeping bag liner! A sleeping bag is an investment—usually an expensive investment. The insulation in a sleeping bag, whether down or synthetic,… Full review

Deuter DreamLite 500

rated 5 of 5 stars I can't believe that someone hasn't already reviewed this sleeping bag! These are my GO-TO warm weather bags, and the ones I use more than any of the others! I have two (2) of these bags, and I highly recommend them to anyone looking for a lightweight, warm weather only sleeping bag! This is the color scheme of the bags that I own. Mine don't look quite as tapered as the manufacturer's stock photo. And mine are not quite as "pretty" anymore, either! Lol. BUT, I purchased these bags in May of 2010,… Full review

The North Face Lynx

rated 4 of 5 stars Packs down to less than a volleyball in size. Comes with compression sack. Warm even below its rating (35 degrees). Great summer bag. This is a good entry level summer bag for the hiker looking to get out into the woods w/o the 450 dollar bag, 500 dollar tent and 300 dollar backpack. Compresses to a respectable size. Allows you to go into the woods with a 50l pack given you have the right clothing and shelter. I would buy it again. Full review

The North Face Dolomite 40/4

rated 4 of 5 stars Lightweight, packable/compressible, can use as a quilt... well made. Bought this bag for summer camping since I have only 20 deg bags. Stayed warm down to high 30s. Below that I was chilled a bit. Great deal for a bag of this weight and quality, couldn't ask for more. Full review

Sierra Designs Backcountry Bed Duo SYN 1.5-Season

rated 5 of 5 stars Someone who sleeps with a partner will find this bag has such great design features that they will know the person who designed it loved and hated doing this many times in the past. tThey distilled all these experiences in one great couples bag! I am 5'8" and weigh 240 lbs and my partner is 5'5 "and weighs 130 lbs. Most of my weight is in the belly, cursed that I am! Considering my proportions, this bag was just a little snug at the mid-section when laying flat next to my partner...not too snug… Full review

Marmot Unisex Mavericks 40 Semi Rec

rated 4.5 of 5 stars Simple but great bag. Forthright about the temp rating. Light and packs well for a synthetic. Cost effective. Warmth: Tells the minimum and comfort rating on the bag 25/40. Does well with the rating. Warmth is distributed evenly. Fit and Comfort: The material is very comfortable. It is roomy in the torso. Leaves off the hood to reduce weight.  Entry and Exit: Very easy in and out. Zipper doesn't stick. Moisture: I've never had an issue with moisture. Packability: Packs down to 8 X 10 Loft: Average… Full review

Ozark Trail Sleeping Bag

rated 1 of 5 stars I bought the zero degree bag and nearly froze to death. It cost me a thru hike last year. This is more like a 40 degree bag rating. Day one, night one...the zipper tore and cord in hood broke. It was 4 degrees and I nearly froze. Day 2 ...it was closer to 6 degree and I froze...I had to hike into town, replace the bag. Not worth using as toilet paper. I could have gotten better quality from a teenager's home ec project and lighter weight. I would not recommend this product to anyone unless I wanted… Full review

The North Face Aleutian 50/10

rated 4 of 5 stars Great price. Packs down very small. A very good warm weather bag. Can fit it in a small Kelty compression bag (color listed as Curry). Packs down to smaller than 10" x 5". Full review
