Recent 3-Season Synthetic Sleeping Bag Reviews

Teton Sports Tracker +5°F

rated 3.5 of 5 stars Nice for the price. Not a 5-degree bag. Long is not long. Long is not long. At 5' 8" and chubby, I fit snugly. I can't see anyone over 6 feet fitting in the LONG bag. Zipper sticks at the top when closing; opening was easy. Used several times in the low 20s and started feeling chilly. Not a 5-degree bag; I don't think it would be good below 20 degrees without a liner or extra clothes. Drawstring on the hood worked well; felt no air leaks along zipper. Pocket inside by chest is too small for glasses… Full review

The North Face Elkhorn

rated 3.5 of 5 stars This sleeping bag is one of the best designs that I've ever slept in. It comes close to the comfort rating if you wear some insulated clothing to sleep. It's a bit bulky and its weight works against it. Warmth: The bag has a 0°F (-18°C) rating. Normally, that rating is the lower end rating that identifies the temperature at which the bag will keep you alive. As a general rule, I add 15°F (9.5°C) to that rating to provide a temperature "comfort" rating. According to those parameters, you should… Full review

Mountain Hardwear Pinole 20°

rated 3 of 5 stars Decent bag with some concerns. I bought this bag because I wanted something a little smaller. Sacrificing warmth I went for a three-season bag with the option of adding a liner. If in higher elevations, as I usually am, some long johns and merino were enough to keep me toasty. My only issues are the zipper must be carefully opened and closed so as to not get caught, which it is prone to do. The hood system is simple and effective, but being a spinner when I sleep I tend not to use it or else I get… Full review

Teton Sports TrailHead +20F Ultralight

rated 4 of 5 stars Men need more shoulder width. This is a well engineered bag! It's comfy with plenty of room at the head and foot box. However, its width of 32 inches is too small for amMan 5'10"+. I couldn't relax having such a confinement at my chest and shoulders, making me feel that I was putting too much stress on the bag. While in 30 Degree F. temps, the bag performed well. I was warm and not overheated, but my feet were chilled. Doubling my socks remedied this dilemma. I would highly recommend the Trailhead… Full review

REI Men's Lumen +25

rated 4 of 5 stars Comfortable, long lasting three-season sleeping bag. Purchased in 2012 when I first got into backpacking. Wanted an affordable bag for backpacking. Packs down (with aid of a compression sack) to about the size of a basketball. Relatively heavy, but very warm and cozy.  Have used a lot in five years and it's held up great. Eventually would like to upgrade to a lightweight down, but for the money, it's hard to beat this bag. Full review

Marmot Trestles 20 Semi Rec

rated 4 of 5 stars After doing some research, I wanted a bag that was synthetic and wasn't a tight fitting mummy bag. This fits the bill. The double zippers are great and allow the bag to breathe on hot nights. I've never been cold with this bag, even when the temperate outside dips into the 20s. I have found that in that range, the bag does take sometime to warm up inside. As everyone else has said, the zippers do tend to get caught on the fabric a lot. The glow-in-the dark zipper finders are also pretty weak too. Full review

Teton Sports TrailHead +20F Ultralight

rated 4 of 5 stars Very comfortable and warm material. Good bag for the price. A bit snug around the shoulders. Lightweight and well built. Fits well in my backpack compartment. It's also a bit too long for me (5'8"). I have used this tent twice this spring/summer already since I purchased it. The first time was in the spring around Mother's Day and I was comfortable the first night when the temps were above 35 degrees. The second night it dropped down under and I found myself a bit chilled, not too bad, but just… Full review

Mountain Hardwear HyperLamina Flame 20

rated 4 of 5 stars I purchased this bag for sea kayaking in the NW. This bag is warm, compresses small for a synthetic filled bag, and has a roomy footbox and a relaxed mummy design. First off, I have used this bag on multiple trips, both backpacking, sea kayaking, and car camping. I feel I have used it enough to give a solid review of its features. This bag is light enough to carry and compresses small for a synthetic bag. It has no noticeable cold spots. The baffles seem to hold the fill in place well. The best… Full review

Wiggy's Sleeping Bag

rated 1 of 5 stars Just got off the phone with Jerry with a problem with a 0-degree bag not keeping me warm in 35-degree weather,  So asked what he suggested, to my surprise no help with possibility of a problem with the bag. His fix was buy fishnet long underwear for 80 dollars. Too funny! OK, I will use this bag for my dog to sleep on and go buy a good bag. Full review
