Rated 5 out of 5 by from Kept me warm at 27 degrees I used this bag for the first time last weekend on the North Country Trail near Hodenpyl Dam. The low temperature Friday night was 26.8 degrees. With a thin liner I was warm even though I get cold at night easily. The zipper works fine. The draft tube is made of a stiffer material which keeps the zipper from catching. It compacts almost as much as my old down bag, but I would have been freezing last weekend in my old bag.

Rated 5 out of 5 by from Outstanding bag! I've had this bag for about 10 years (I don't remember exactly how long) and highly recommend it. I've used it in a wide range of temps and conditions. For me, the larger shoulder size means more versatility. I've used it from 15 degrees to in the 70's, all comfortably. It has plenty of room so I can comfortably wear fleece or whatever for the cold temps or use it as a quilt for the warmer nights or with my gf. I also like it as a quilt in my cold Chinese apartment. It has a wide comfort range because the down can be shifted. Mine is in pristine condition except for a small tear where I caught it in the zipper. I made a field repair, no problems. Other than that the Pertex fabric is great, the zipper is like new, and the loft is like new. A really versatile bag with a much greater comfort range than 30 degrees.

Rated 5 out of 5 by from Perfect 3-season bag Packs super small but cliffs nice and big for warmth. Not sure if this is recommended or not, but I zipped my summer lite to this bag and my husband and I were roasty toasty warm and had room for the dogs inside our bags without compressing the stuffing.

Rated 5 out of 5 by from hope this model is still available in 10 years if i ever need another I am 6'3" 260ish, mostly muscle and very broad shouldered. I was hesitant to get any costly sleeping bags because i would hate to rip another out in the shoulders, but got sick of carrying around heavy cheap ones on long hikes, so with the helpful advice of the local moosejaw manager we decided to order one to the store and check it out. Other than the color(which i won't really complain about) this bag is absolutely perfect. There is enough room to move my legs and arms inside, and it isn't an awkward bag for a side sleeper. It also kept me nice and toasty in the mid 20's with just a t-shirt and boxers. ,,It is light enough that anyone could carry it and stuffs down nearly to the size of a flannel sleeping bag, and its about the same weight.

Rated 5 out of 5 by from This WM. Mega lite. Mega awesome. My Mega lite WM is going on 3 years and it is still putting a smile on my feeling smart face that purchased this awesome bag. My number one reason Im suggesting everyone buy this bag is the shoulder cut! At 64 in. I guess Im heating up wasted space they say since Im not big and broad shouldered. But ....I say This bag is keeping me toasty down to 30 with just a fleece hat and thin base layer on and that extra room. When I need to go lower temps I put on my down sweater and I am still toasty and I still have room to roll over freely. Freedom in a lite weight quality made in the USA down bag. Ditch your old cold ratty heavy bulky straight jacket bag. Mega lite is just right!

Rated 5 out of 5 by from Best overall, multi-purpose bag around!! Love this bag!! Excellent craftsmenship, killer weight to warmth ratio, nice and roomy, pack down small. Very versatile bag. Have used in varying temps. Colder weather I break out the thicker liner and I can take this baby down the the 20s. Most of all i like the big girth this bag provides for a mummy. Im a side sleeping and move around a lot and this thing kills. Well worth the extra coin. And its Made In USA!!

Rated 5 out of 5 by from Best sleeping bag ive ever owned Love this sleeping bag. I also own the western mountaineering summerlite which i also love. The mega lite is a bit more lofty and most definitely warmer. Packs super small and lite. You can just smell the quality coming off the bag when u lay in it. Not the nasty chemical smell alot of bags give off but a smell of great quality. Cant wait to use it on my AT thru hike in 2014!!! Would rate it closer to 20 degrees not 30 as western mountaineering rated it. Very expensive but worth every penny. I see this bag lasting my entire life its that well made
