For the price, it's a great sleeping bag. Warm underwear was necessary for 32F nights, and I had to put fleece top/bottoms for 20F nights - which is fine with me.

Unfortunately, after 2 years of use it's getting flat.

I've had this bag for a few years and really like it. I've spend many nights in sub-freezing temps and stayed comfortable everytime. It has held up well over the years. When I purchased it Campmor threw in a free Therma-Rest pad, so it was really a great deal.

Campmor always provides excellant customer service.

I've had this bag for about a year now. I've found it a little warm above 35-40 degrees. It kept me quite comfortable in the Sierras when it got down to freezing. I haven't had the opportunity to use it in less than freezing temps. I haven't had any problems with the loft or zipper as some have but I haven't had it as long as some. I'm 6'2"/195lbs and am comfortable with the room in the bag.

Well...let''s just say that it should be expected that all gear purchases don''t work out. This sleeping bag lost it''s loft after less than 2 years of moderate use. I first became aware I had a problem on my hands when I woke up cold on a 30 degree night. As someone who sleeps hot, I was surprised, but a closer inspection showed this bag was going flat, flat, flat despite attentive care. I am seeing similar behavior in my wife''s Rosa bag, which only managed to keep her comfortable on nights above 40 degrees (she is a cold sleeper). These combined poor performances leads me to give this line of Sierra Designs bags a very poor rating. In both instances these bags have failed to do their job. I love their tents and own two, but I will not bother with another of their sleeping bags. I suppose their higher-end bags may suffice, but I''m looking elsewhere because these bags didn''t perform as promised.

Life is too short to to haggle over a trade when you don''t have confidence the replacement will be any better. So I haven''t tested their system and have replaced these bags with highly rated Marmot

Used in the middle of a hot Georgia summer (July), hot/rainy at 4000 ft (August) and feet in the North Georgia Mtns on a wildly windy and cold (25?) weekend. Back stayed toasty. It packs to about 19x5 in its stuff sack, smaller with a compression. Weighs about 2.5 lbs. and is very comfy. I did snag the zipper once, but must say I was in a hurry when I did it. I have no complaints about this bag.

Customer Service

Campmor customer service is superb. I ordered this bag at 109.99. A month later they had a price drop to 99.97. I emailed Campmor asking if there was anything they could do and was immediately notifi

This is an incredable bag. It is very water-repelant. It works well in all three season use. the cut of the bag is just right for the somewhat closterphoblic backpacker. I find the bag slick against a sleeping pad. I would recomend using the intivative pad lock system with the sleeping bag. An all together great bag.

Bought on sale at REI and returned for a refund after 1 weekend trip. To be fair, I had never tried a Mummy bag before and just wasn't up to the contortions needed to zip it up. The zipper jammed about every inch, which pretty much eliminates the mummy approach if you can't seal it up. The zipper design, tape and draft tube appear to all conspire together to make this bag a bear to close. I do feel grateful that it all jammed up on the way up, rather than locking me in for keeps. No way I'd sleep in this on a solo trip without a good knife or cutting torch in the bag with me.

Customer Service

REI cheerfully refunded my money without so much as a bat of the eye. Lots of my pals bad mouth the big chains, but they have the size and assets to stand behind what they sell 100%

Let me preface my remarks with the fact that I sleep warm and I've only used the bag for one trip of two nights, so far. Obviously that doesn't give me a LOT of experience with this bag. That being said:
I was very satisfied with this bag. The two nights I used this bag, it was 13 and 10 degrees F, BELOW the temp rating and I was toasty warm. Granted, first time use, but very comfortably warm while in the snow. The weight and compressibilty are outstanding. 15 deg bag under 3 lbs! Sounds good to me.
Only complaint, the zipper snags constantly, even on the tape to help prevent snagging. Very annoying.

The ""Wild Bill"" is a good bag. It is relatively light and I have never been cold while using it. I live in Arizona and do a lot of camping in both the desert and mountains. The temp of this bag is just right for winter in the desert and summer in the mountains. My only complaint is that the velcro piece that helps close the hood gets stuck to the bag material if it's not set perfectly on the other velcro piece.

Customer Service

I'm mad at Sierra Designs for ""selling out"" and putting their products in Popular Outdoors stores. The problem with this is that the small specialty shops just can't compete with the big chain. Thus, Popular sells the bags for less and people get all the good info from the small shops and then go buy from Popular. The moral, SUPPORT SMALL BUSINESS!!! They are the ones giving you the graet service.

This bag is warm, comfy, and light weight. I agree with the previous review regarding the velcro strap, but that is only slightly annoying. Great bag.
