Western Mountaineering MegaLite 30 Sleeping Bag Reviews:

Positive Reviews:

This bag is just great. I am 6'2 185 lbs and bought the long size. I am a side sleeper and prefer space inside of my bag; this bag fits my needs perfectly. Lofty, warm, light, and smooth are the four words that sum up its features. I can't believe a bag this spacious actually fits into the included XS stuff sac. I especially love the smooth inside/outside face material, it just feels very soothing to the touch, unlike the Montbell u.l.'s tissue like material. Few people talked about the function of a smooth face material on a sleeping bag, but the smoothness of the inner surface lends itself to allow easier tumbling and turning, without taking the bag with you.
My wife and I can even use it unzipped as a comforter, and achieve decent warmth and comfort. It also shows minimum down leakage, which is a serious problem in other bags that I have owned. This is one piece of luxurious equipment that I can honestly say well worth the money.

this is a high quality sleeping bag if you do buy it and find that you are cold with your 30 degree rating and don't think you are warm enough western mountaineering is a solid company send the bag to them ask them to stuff your bag with a bit of extra down and boost your temp on your bag. i love this bag mainly cause it is so light and with my compression sac i can squeeze this guy in my small light day pack and still have room for the rest of my gear. i bought this cause i was cutting weight from my pack and got all new gear with super light wt in mind. i say get it like i said if it not as warm as you hoped send it in and get a boost of down.

Spent two weeks sleeping comfortably in 30 degree weather. I never once felt the chills and most nights never even had to zip up all the way. Granted, I am a very warm sleeper, but I would take this bag down to 20 degrees with very little problems. Western Mountaineering makes a no frills (and no chills) bag that will last a lifetime as long as you take care of it like it takes care of you. The price is steep, but it might be the last bag you ever buy (or, if you are like me, just the first in the entire WM lineup). Add to all that the fact that it is Made in America and you should feel very warm about your WM purchase.

One of the biggest mistakes of my life was trading my 30 degree bag for a 35 degree. But bags are exceptional and both have accompanied me on Appalachian Trail thru-hikes, but I miss the full zipper feature that the Western Mountaineering MegaLite 30 degree bag has. I sleep very warm so my 30 degree bag with a silk liner keeps me warm even when the temperature got in the 20's. On warmer nights I would unzip it and use my bag as a quilt. It compresses down nicely and recovers it's loft quickly. The life time warranty is a great piece of mind, but I have yet to have any problems with any of my western mountaineering bags..

This is my first WM bag and I'm hooked. Just took it on a 2 night backpacking trip. Super lightweight & compact. I'm a woman, 5'2 and the 5'6" is perfect. It is roomy in the shoulders good if you move around alot at night and/or for warmer temps but not efficient in temps below 40 (I stuffed my extra clothes in the space to make it work in upper 30's) I do like the bag, but because of the roominess, this will be my warmer weather bag and I'll probably get the Apache for more efficiency in cold wx.

Great Bag - As good as it gets

Great bag. Light and fluffy. Wider cut for more room without much of the weight penalty. Materials and construction is top of the line. Out of stuff sack it gets back and expands quickly. I guess at this weight any bag is frigile and need to be cared for (but is you pay as much as it costs I guess you would do it). Full lenght zipper is great for warmer night. Didn't test it to the extreme but it served me well on 11 days trip in Utah / Arizona.

Perfection? I've had my megalite for three years now, and I couldn't be happier. I've used on everything from multi-day backpacking trips, to multi-day cycling trips and three season recreational camping. I've never had a problem with it, and don't think I ever will. I purchased mine at another store, and they only had the 6'6" model, so I'm swimming in it as I'm only 5'4", but that doesn't effect the performance. Overall, I don't plan on buying another bag from any company except WM, superior quality and pack-ability.

Evan Tougas at Backcountry.com on 03/14/2011

Received mine last week and took off for two nights. It was 38f and damp as is usual in the Sierras this time of year. I was totally warm and dry.
I have a MontBell 32f that cost $40 less and I was freezing last month. Big deal..save $40 for Chinese junk. I also had another high end brand 32f bag...same thing..Chinese junk.
I also have an Alpinlite. It is too much unless around or below 32f. WM bags are the only ones with real temp ratings.

mik5620827 at Backcountry.com on 06/05/2012

I have been using my 6' mega for 2 yrs and am so pleased with how the temp rating is right on but I have easily pushed the temp rating by wearing long unders. I have put on my down sweater inside it and been too warm so Im not sure where the bottom temp is on that combo.You can only do that because of the generous cut. Buy this bag and feel like a very smart and patriotic outdoorsperson!

Steve at Backcountry.com on 02/24/2013

I'm convinced !

I bought this bag after a lot of research. I'm going to use it for base/car camping and backpacking. I just returned from 4 nights at Elkmont Campground in The Smokies. Temps ranged from 40 degrees down to the upper 20's at night & I was quite comfortable.... I can't wait to get out again. I think it's worth every dollar...
Also: This is a 30 degree bag; not 32 degrees. Please correct the description...

Negative Reviews:

The build quality, the quality of the down that Western Mountaineering use (850 fill-power Goose Down), and the design itself are second to none. They are all handmade and usually made to order in northern California, which is a rarity these days. I bought the Megalite because I am extremely tall (6'6'') and broad shouldered, and I fit perfectly inside with room to spare. It packs down to the size of about two, 1 liter Nalgene bottles, and even smaller if you have a compression stuff sack. It weighs next to nothing. Everything else aside, this bag was simply not warm enough for its rating. I gave it 5 trips into the backcountry before I decided to send it back. During 4 out of 5 of those trips the temps did not dip below 40 degrees and I was still freezing, and I run EXTREMELY hot. I thought I would spring for a top class, ultralight piece of kit after twenty years with an old North Face Foxfire, but $420 is way too much to pay for something that does not keep you warm. In retrospect, if I was to buy another Western Mountaineering bag, I would buy the Alpinlite, but a bag this expensive is an extreme luxury. I'll stick with my old Foxfire for now.
