Recent 3-Season Synthetic Sleeping Bag Reviews

Mountain Hardwear Pinole 20°

rated 5 of 5 stars Great bag for the budget backpacker. Compresses well for a 20deg synthetic, and keeps me warm down to rated temp! My son and I needed a couple of packable, cold weather bags for backpacking with his Scout Troop.  Considering budgeting for outfitting us both with packs, bags, sleeping pads, and miscellaneous gear, we were looking at less expensive bags. Throw in that we're in the Southeast, where humidity and rain are always in the possibilities, down bags didn't make sense, either. I put some research… Full review

Therm-a-Rest Capella 20

rated 1.5 of 5 stars Bulkier than expected. Overpriced. Way overpriced. "System" of two stretch bands to secure to same brand of matched sleeping pad fails. I slid off every night, finding hip or shoulder on ground. Bag slides OFF the pad length-wise — down off the foot of the pad, too. Too hot for temps in 40-50s. Comes with a simple stuff sack, should have a compression sack. I bought one and it compressed the bag to at least 1/2 of the provided stuff sack. The bag was too bulky otherwise. Despite being made for… Full review

Mountain Hardwear Men's UltraLamina 32°

rated 4 of 5 stars Light, packable. I love this bag. I used it for a 5-night trip to Clear Creek in the Grand Canyon. The coldest night was about 38 degrees. I wore several layers most nights as the temp was low 40s high 30s, and I wasn't freezing. The thing I love most is how small and light it packs. Carrying everything around for 6 days, it's the weight and room it takes in my pack that matters, and this bag is excellent in both regards. I guess it could be warmer near the temp rating, but having researched bag… Full review

Cascade Designs Therm-A-Nest

rated 5 of 5 stars This tragically discontinued "kid'tainer" is one of the most ingenious sleep systems ever invented for lightweight tent camping. Manufactured in 1993, this 1 lb. 9 oz. sleep system by the makers of Therm-a-Rest is a great option for parents who want to backpack with their little ones. The upper portion is basically a sleeping bag. The sheet-like lower portion forms a pocket for your 3/4 Therm-a-Rest mattress (not included). It is 34"x60" which fits a child up to 54" (about 10 yrs. old, 70 lbs.). Full review

Teton Sports Tracker +5°F

rated 4 of 5 stars Great cold weather sleeping bag. Nice compress-ability and the stuff sack is good. I purchased this sleeping bag to replace an older 0 degree synthetic from Eureka. This bag has a similar rating at +5 but compresses way smaller than the Eureka bag. The material of the outer shell is a nice durable ripstop nylon. The inner lining is different, it has a nice texture to it and isn't like most bags with the shiny nylon feel. There are zipper pullers inside and out to make the closing easier but the… Full review

Mountain Hardwear Crazy Legs 20°

rated 4.5 of 5 stars Mountain Hardwear eggplant Crazy Legs 20 degree left hand zipper mummy bag. I've had my eggplant left-hand MH 20 degree bag for about 15 years and though I've had to wash her like seven times (old roommate's cat puddled on it) she still keeps me warm in the PNW nights and compresses down and is super lightweight. Full review

The North Face Men's Cat's Meow

rated 2 of 5 stars This is a very popular yet overpriced and underperforming sleeping bag best used during warm weather. The foot box is very small, while the torso area is extra roomy. The small zippered breast pocket is very useful for keeping earplugs or hearing aids, until the material gives out after a few months of use. The small flap of material that covers the soft nylon zipper is at the worst length possible, guaranteeing that the zipper will snag on almost every use. I am not a North Face fan after using… Full review

Marmot Men's Trestles 15

rated 4 of 5 stars This synthetic bag will take you where you need to go, on a budget and in style. Its rating runs true (depending on how warm of a sleeper you are, of course), and will stave off the cold even in shoulder seasons. It is a must-have sleeping bag for those new weekend warriors and those on a budget. I've had this bag for a year now and am very pleased with how it has taken care of me. It is a great bag for those needing warmth but not ready to make the plunge into pricey down bags. I've used it in… Full review

Eureka! Kaycee 0ºF

rated 4.5 of 5 stars Nobody likes to be cold when they're camping. Having a good sleeping bag to keep you warm all night is even more important when you are winter camping. I recently tried out the Eureka! KAYCEE Zero Degree sleeping bag on a winter trek in Ontario and stayed warm all night long. The Eureka! KAYCEE sleeping bag is a performance mummy sleeping bag rated to a low of zero degrees fahrenheit  or minus 18 degrees celcius. On a recent winter outing I used this sleeping bag one night when the temperature… Full review
