Recent 3-Season Synthetic Sleeping Bag Reviews

Mountainsmith Crestone 0

rated 2 of 5 stars Should not be rated 0 degree Fahrenheit. Maybe 0 degree Celsius because it may keep you alive at that temp if you wear some warm clothes with the bag, but even at 40 degree Fahrenheit it would not keep me warm with several layers on.  Full review

Marmot Men's Trestles 15

rated 4.5 of 5 stars Great bag from a great company at an even better price. Bought one for myself last fall. I got about seven trips in it so far, all on the AT or Mountains-to-Sea Trail in East Tennessee and Western North Carolina. The coldest night so far was 25 degrees and I had no issues with getting cold. You can get bags that compress smaller and weigh less, but not for 104$. The zippers can be a pain as most previous reviewers noted, however I think I have figured this out just through trial and error. Leave… Full review

Mountain Hardwear Pinole 20°

rated 4 of 5 stars The Mountain Hardwear Pinole 20 is a fine 3-season sleeping bag. I purchased this bag after much research on 20 degree bags. Some reviews had me second guessing. I'm glad that I ended up going with this product. I backpack/car camp/canoe camp in the mountains of East Tennessee and Western North Carolina. For me it made sense to go with a synthetic due to the humidity and moisture that I experience in my area.   Ready for use in the ever humid valley of South Fork Citico. I have spent an honest… Full review

Snugpak Jungle

rated 5 of 5 stars A roomy, versatile, lightweight sleeping bag with unique features that can also be used as a hammock top quilt. I bought the Snugpak Jungle Bag to include in a lightweight hammock camping system and to also serve as a summer weight sleeping bag for use in a bivy sack or for just under the stars all by itself. Originally I had considered the classic U.S. GI issue polyester filled poncho liner or patrol bag for this purpose but new and genuine army issue gear has dramatically escalated in price… Full review

Mountain Hardwear Lamina Z Flame 22°

rated 2 of 5 stars Seems very damp, clammy non breathable. Poor zipper. Thermal zoning is nonsense. Good quality construction, but uncomfortable due to above. Great construction quality, but the thermal zoning idea is the invention of a very clever monkey. It makes the bag hot in some places and cold in others, so the comfortable temperature range of this bag is limited. I have tested this bag extensively and had the same results almost every time. When I first tried it out it was like sleeping in a non-breathable… Full review

The North Face Men's Thunderhead 3D

rated 3.5 of 5 stars A nice lightweight entry level synthetic bag for 3-season camping. I bought this bag for my son and he has used it for the past 3 years. He really enjoyed it but has recently traded in for an upgraded model. I have used this bag a minimum of 5 times myself ranging from spring to fall. We compared notes and this is what we have come up with: Warmth: The bag is rated to 20°F. North Face touts, "Whether you’re camping in a goliath blizzard or huddling against cold, damp air, this awesome 20° bag… Full review

Wilderness Experience Latok

rated 5 of 5 stars The Latok was the first non-quilted Gore-Tex sleeping bag ever made. I designed it for Jim Donini's expedition to Latok 1 in Pakistan in the late '70s. WE didn't make very many, so enjoy your Latok as much as I have, cheers Greg Thomsen co-Founder Wilderness Experience. The Latok is a very warm sleeping bag because the outer shell is a non-quilted layer of Gore-Tex fabric—so no heat loss through the quilt lines. There is also a layer of aluminized foil sandwiched between the Polarguard insulation… Full review

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
