This was purchased primarily for my boy scout and I on troop campouts. Highly recommended as the best balance between size/weight and price that can easily be packed in standard frame backpacks. Don't spend the extra $150+ on high-end down backpacks that may be slightly smaller to pack. Shell is high-quality lightweight nylon. Slept very comfortably on campout that was <40F.

Purchased in Feb. 2010 for use as a 3-season sleeping bag. Used two nights in 60 deg. F house. Too warm while zipped. Perfect for unzipped use. Used on March 20, 2010, during a low 40 deg. F nighttime backpacking trip in NY state. While wearing sweat pants, tee-shirt, sweat shirt and socks, I was mostly comfortably but just a little cool. Therefore, I will not use this sleeping bag for lower than 40 deg. F nights which is fine for my intended use. As the literature states in the sleeping bag box, the 20-deg F rating is a survival rating which means to me being heavily clothed while using it at this rated low temperature. This was my first mummy sleeping bag. I am a 5' 6", 140 pound male, and felt a little claustrophobic in the bag. But I wanted a compact and light weight bag, so I will get use to the tight quarters in the mummy bag. For someone much bigger, I recommend rethinking whether or not you want a mummy sleeping bag. The bag dimensions on the label is 84" long, 32" wide at chest, and 20" at feet. From what I have seen for mummy bags, this is rather typical. Although, when I measured the bag, it was 2" smaller for each of these 3 dimensions. I wanted a nylon inner & outer shell bag. This sleeping bag was advertised as such on the OverStock.com site. However, when I received it, it had a polyester inner and outer shell. I like nylon because I expect it to wear better than polyester and it doesn't smell as bad with any contact to perspiration. Since most light weight bags that I investigate are polyester shells, I assume that there must be other advantages that I am unaware of. The bag comes with a nice compression sack which measures 8" diameter and 14" long with the bag in it. This is a nice compact size. The bag compresses rather easily in this sack. As for weight, the bag and compression sack weighs approximately 3.5 pounds per my bathroom scale with a fill weight of 1.5 pounds per the label. I was looking for a bag under 3 pounds but it is rather light compared to my other two sleeping bags (i.e. 5 & 8 pounds). Overall this bag meets my expectation. I am looking forward to many years of use with this bag. Good luck to you in your purchase.

This sleeping bag kept me quite warm and is oh-so-light! I am a backpacker and really appreciate lightweight gear. This thing compresses to nearly nothing so that it fits easily in a 65L pack (and probably a 55L pack), and, it bears repeating, weighs next-to-nothing.Probably wouldn't keep one warm at 20 degrees F unless you were bundled up in a few layers of clothing, but no sleeping bag I've ever come across has ever met the stated temperature rating, so this really isn't an issue. I slept in long underwear (my usual camping sleeping attire) in 40 degree temperatures in this bag and belt perfectly cozy.Workmanship seems up-to-snuff and it seems it will last for some time with average use. As an FYI, I backpack/camp 1-2x/month and I have no doubt this bag will last a few seasons.

Great price, used bag for a overnight hike in NC and the low weight and pack size was great!Mostly warm enough for NC mountain nights.The zipper snags a bit, but that's the only problem I saw.

Son went on a two day hiking trip. He was very pleased with the weight and size. It was warm enough for him to unzip the lower zipper and stick his feet out.

Seems to be very light and works well. The compression sack comes in handy. Don't leave it in the sack when storing since you are putting undue stress on the seams of the sack. I put my sleeping bag in another satchel to let it fluff. I'm 6'0 and 160 this fits me fine. The zipper is not the greatest quality, but it works. Could be a bit trouble some zipping up.

I've used this bag a couple of times now, sleeping indoors and car camping in Yosemite with temps in the low 40s and have been toasty each time wearing pajamas. The bag packs up very small and saves me a ton of space over my older Kelty mummy bag, too. One item that isn't mentioned in the description of the bag is that this bag has a LEFT closure, with the zipper on the left side, which has been an adjustment for me. Overall I've been very pleased with warmth and quality of the bag and feel I got a really good deal. I also have a Ledge Scorpion tent that I am enjoying as well. If I was to nit pick for issues I've had, I'd say: * The neckline on this bag is a little on the high side, fitting above the shoulders, causing the zipper pull to be in an awkward position for a right-handed person like myself. * To close the zipper the bag sometimes needs to be straightened out. Otherwise it will temporarily snag about half way up. To remedy, just zip down a small amount, straighten and pull closed. As I said, I've been really pleased with the warmth, weight and size of the bag.

Just as described, this is a great lightweight, compact bag for an excellent price. I took it camping this weekend and slept outside (mesh tent, no fly) in 40 degree weather with wind, and stayed toasty warm. The zipper is a little cheap looking and the material is not super sturdy (might be easily ripped) but with a bit of contientous care I'm sure it will last for some time. No complaints, very happy with this purchase!

I used this sleeping bag while camping in Peru. The temperature dropped below freezing (made apparent by the frozen rain on top of our tents) and the sleeping bag kept me warm. However, the next morning I had feathers on me - not many but quite a few. Also, I was fighting with the zipper everytime I needed to come out of the sleeping bag. I purposely left the sleeping bag in Peru. If I go camping again I will buy a different brand.

I purchased this as an addition to my survival bug-out-bag, and was very happy when it arrived. I wanted something of decent quality that was compact and light weight. This definitely has those qualities. I have not yet used it, but will be doing so very soon. Based on the other reviews, this line seems to do very well in moderately cold weather conditions. We will see. But if you want something that wont take up a ton of space in your bag, this is it.

Good bag for the money. I wouldn't use it for any less then 40 degrees. Slept in it last night at 39 degrees outside. We were in a tent. I was perfect my wife got a little cold. I'm a hot sleeper. I'd would have had to layer up to go colder though.

• How accurate was the sizing? Right on.
• Please tell us about the quality of the product. Quality is good so far. Bought 2 of them one of the draw cords was stiched up so it wouldn't draw. Carefully removed the stitching to free cord and stiched it back up. Easier then returning.
• Was the product free of any manufacturer defects? Just the draw string that was stiched up in a seem. Easy fix.

So it is really light and it packs really small, especially with the compression sack. The only thing is that it is not really a 20 degree bag. it has a note inside that tells you that this is the survival temp. Its so thin and light because its not really a 20 degree bag. its probably a 30-40 degree bag

I thought this sleeping bag was a great deal for the price. I used it in 50 degree temperatures though, so I cannot attest to its use in cold weather. It was very light and easy to roll and fit in my pack great.

I bought this for my 10 yr old son, knowing he'll be able to use it as a young adult too. I climbed in it to check it out. It is a little tight for my tastes, especially in the foot box. I prefer a little more room. I'm 5'10", 180lbs. But the zipper doesn't snag, just as others noticed. We haven't field tested it yet, but the stuff-sack seems durable. We won't be camping in sub-zero temps, so we're not concerned about warmth.

My Grandson is thrilled with it! He will be using it for 4-H events and family camping vacations.

This thing is light, it packs small, excellent for hiking. It is an average size, and it is super warm. Bought this for my Boy Scout son, and he camps most nights outside of a tent, and has never complained about being cold, even in temperatures below 30. Excellent all around, all purpose sleeping bag.

This was purchased as a gift for my son in his 20s. He has not used it yet, but he really likes it a lot and is looking forward to taking it on his next outdoor trip. He likes that it is light-weight, compact, and warm.
