Rated 5 out of 5 by from If Cobra Kai had to choose a sleeping bag, this is the one they would pick. I like to think of the WM Alpinlite bag as my fortress of solitude! This sleeping bag instills fear and commands respect. It's baffles are lush and the extra room in the shoulders and legs provides an impenetrable sanctuary for those feeling down in the dumps. I took this bag on my A.T. Thru-hike, PCT Thru-hike, and the South Island of New Zealand and it lasted the test of time. It’s worth every penny you can muster and if anyone ever said anything bad about this bag (in front of me / in person) I would straight up bitch slap them. I love this bag and so will you…..Lancelot had Excalibur…. You can have the Alpinlite. BUY IT!!!!!

Rated 5 out of 5 by from Well-designed, Luxurious & Cozy In low rainfall areas like CA, you can afford the luxury of goosedown. Wow, does it feel good!,,Design: The bag lofts high. A stiff tape makes the zipper snag-proof even if you are zipping up in the dark while half asleep. The 5'6" model is roomy for me at 5"2" with space to store whatever needs protection from cold. It packs easily in a 60 liter pack. And what if it rains? A tent & a good sleeping pad will get you through. This year I am upgrading my Thermarest Z pad which in a pinch collected driven rain in the wells of the pad to an Exped mat that will keep me 2 3/4" off the tent floor. Check it out.,,One Wish:,,For loops to secure the pad to the bag for restless sleepers who roll off.

Rated 5 out of 5 by from Livin the dream Love it. This bag is champion. I'm 6ft, 210, with broad shoulders and a thick chest and this bag fits perfectly. I have the 6ft bag as well, if your much over 6ft tall go for the larger bag. It's warm, super light, packs down small and my favorite quality is how easily it zips. The zippers will never catch!! If your a bigger guy, these are the bags you want!

Rated 5 out of 5 by from Hey folks....... It's a Western Mountaineering product!!!!!!! Need I say more. Anyone who has a product with the manufacture's name tag on it knows what I'm about to say is true. It's super light weight but toasty warm. I love the no jam pull zipper. Very generous cut it allows for a layer of clothing. 800-850 plus power fill down makes this bag super compact so it stows in your pack with minimal space! All I can say is I bought this bag because I have three others by this manufacture.... Got the picture!!!

Rated 5 out of 5 by from Doubt i will ever buy another brand of sleeping bag! Bought this bag after several years of looking for the best bag for its weight. Tried several other name brands knew of western mountaineering from working at a outfitter that straddles the Appalachian trail. Finally bought this bag with the over stuffed down for a 12 self support kayak trip through the Grand Canyon, and couldn't have been happier. The trip was in the middle of January and at times the temperatures were in the low teens but I was warm the whole time. Used this bag off and on for trips between 1-5 days since then and never had a problem! It maintains its loft after being stuffed for extended amounts of time, that being said I always made sure to hang it out whenever I had the time. Bottom line is that yes western mountaineering bags are expensive but if you want guaranteed warmth at the lightest weight then this is the best bag on the market for you.

Rated 5 out of 5 by from Best sleeping bag ever!! Super happy with the Western Mountaineering Alpinlite Long Down sleeping bag. I bought this bag for winter camping in East Tennessee in the Great Smoky Mountains. This first night I used this bag, it was supposed to go down to 26 degrees, as it turns out it was really closer to 10 degrees at 5000 feet of elevation. The Draft collar on this sleeping bag is amazing, the bag was super warm with no cold spots. I am also very impressed with the taped zippers which keep the bag from being zipped up in the zipper. I am a big guy, 6' 2" 250 lbs, and had plenty of girth and extra length for my boots in the bottom of the bag. I would be comfortable taking this bag down to 0 degrees with a base layer and an insulated sleeping pad. The best feature of this bag is the continuous baffles which allow you to move the down on top of the bag when it is super cold, and move it to the bottom when the temps are warmer. 100% worth the price, best bag I have ever owned!

Rated 5 out of 5 by from So comfortable and warm Nothing beats a good down bag and the alpinlite is one of the best! Here is my brief video review of this sleeping bag:,,,,http://www.backpackersreview.com/gear-reviews/sleeping-bags-pads/72-gear-review-western-mountaineering-alpinlite-sleeping-bag

Rated 5 out of 5 by from you need this bag I would say this is the best bag money can buy right now. It is too warm for hot summer climbs but for all other seasons it is great. As soon as you roll the bag out you can tell it is the shitake. Weight is right at 2.0 lbs for the 6 foot. Great quality down better than marmot and it is nice and roomyagain, better than marmot .
