Recent 3-Season Synthetic Sleeping Bag Reviews

Mountain Hardwear HyperLamina Flame

rated 5 of 5 stars Very good. Warmth: Very good  Fit and comfort: I will grow into my bag. I'm a teen. Comfort is very good. Full review

Big Agnes Buell 30

rated 4.5 of 5 stars Comfortable bag that packs down to a small size. I bought this bag with pack-ability in mind. I wanted to put it inside my backpack along with everything else. My old bag is so much bigger, in fact it just barely fits inside the pack by itself. I purchased a Granite Gear compression/dry sack (18L) along with this sleeping bag to get the smallest pack size possible. Now I can put my sleeping bag, tent, stove, hatchet, buck knife, fire starters, and more in the main compartment of the backpack. I… Full review

Sierra Designs Wild Bill 20

rated 4 of 5 stars No complaints. It's been a good bag for temperate climate weather. I've been using this for nearly 9 years, but only a handful of times. Still looks new and works exactly as I expected. I haven't exactly pushed its limits as I'm a fair-weather backpacker whenever possible.  Full review

Wenzel Reverie Mummy 30

rated 4 of 5 stars This bag is used only by my dogs. I bought it for them. They have never shared it. So this review is a bit skewed since I bought this bag strictly for my dogs.  My Dalmatian, Ferrari, was getting very cold at night while camping in October and November for 4-day trips in 2015 (it got down to the high 20's or low 30's at night but was supposed to be in the 40's) and I was snug in my sleeping bag and I felt horrible.  I piled every fleece, every spare jacket, towel, anything to keep her warm the… Full review

NEMO Mezzo Loft

rated 5 of 5 stars FINALLY, after 40 odd years I can sleep ON the pad instead of climbing back on repeatedly through the night. I'm a "mobile" sleeper and always have an issue with staying on my pads. I've tried everything, including some kind of tacky spray to keep my bags from slipping off the pads years ago. I've packed heavier pads just to get that pad wide enough to fall off of a little less. I looked at Big Agnes bags, but never saw one that I felt would be an upgrade from my old North Face down bag. So, I wiggle… Full review

Slumberjack Timberjack 0

rated 5 of 5 stars Big, wide, roomy yet retains heat very well. Very warm and toasty. Did I mention big? I ordered this and went camping with my two dogs. I have been camping before and so has my one dog. But not for a few years. I ordered in a number of things for camping after quite a bit of burrowing through research, comments, reviews, recommendations and personal comments before deciding I wanted to go with a rectangular bag because of the way I sleep and knowing I would use it for primitive car camping (with… Full review

Big Agnes Encampment 15°

rated 3.5 of 5 stars Roomy and comfortable, as long as it's not too cold. Big, comfortable, heavy. They advertise it as a 15° bag, but honestly, I don't know how they get that. Even with the BA inflatable pad, it's only a 35° bag in my experience. Maybe they sleep in long johns. Having said that, it's so comfy I still haul it around, but I'd advise a bag liner for anything under 35°. Nice that it's available in tall. A previous reviewer mentioned mummies as confining, and I agree. It all comes down (for me) to being… Full review

Mountain Hardwear Men's Lamina 32°

rated 4 of 5 stars A warm, compact, and lightweight 2- to 3-season sleeping bag at a reasonable price. I have owned the old model and the new model of the this sleeping bag. The new model is a vast improvement over the old model. I've used this bag for desert camping in West Texas, mountain camping in Patagonia, and everything in between. Warmth: This bag is warm for temperatures 35°F and above inside of a properly protected ventilated tent. At temperatures below 35°F it starts to feel a bit cool. The bag has excellent… Full review

NEMO Mezzo Loft Luxury

rated 5 of 5 stars I bought this bag because I was tired of falling off my sleeping mat in the middle of the night. This bag is fantastic because of the sleeping mat pocket. I slept all night in 30° temperatures and stayed warm and on top of my mat. This sleeping bag has a pocket for your camping mat. It is the sole reason I purchased this bag. It worked like a charm. I never was able to roll off my bags and onto the cold floor of the tent. This will enable me to camp much much longer . Full review
