Western Mountaineering UltraLite 20 Degree Sleeping Bag

Item No. 10079729

The Western Mountaineering UltraLite 20 Degree Sleeping Bag is a three season sleeping bag perfect for a summer bike tour or fall hike through the mountains. The UltraLite is pumped with 16 oz of high lofting down to bring this sleeping bag to a 5 inch loft and can withstand temperatures as low as 20 degrees Fahrenheit. Western Mountaineering uses a full down collar to help keep body heat inside, and the full-length YKK zipper means no gaps for cold air to slip in. The 5 ¼ inch spacing and continuous baffles helps to make the UltraLite 20 Degree sleeping bag extremely compressible, and your pack won't be weighed down with a total weight of only 1 lb, 13 oz. The Western Mountaineering Ultralite 20 Degree Sleeping Bag is the perfect choice for lightweight hiking and biking when cold weather nights are a definite possibility. Bonus Feature? All Western Mountaineering sleeping bags are made right here in the USA.

"Amazing 20 degree bag" 03/10/13

I have the sleeping bag for more than 8 years. they are very nice built, light and warm. However, if you are looking for buying a high end 25 degree bag, Featheredfriends also makes good product. Serious customers should probably compare sleeping bags from both companies and decide which product fit their needs more.

"You'll never feel cold again" 09/17/12

The Western Mountaineering UltraLite 20 Degree Sleeping Bag is the only sleeping bag you'll ever need...just as long as you don't plan on sleeping in the Arctic. It's warm, snug, and keeps you tight all night. It'll be good idea to have a sleeping pad with it.

"Ultralite" 09/12/12

Ultralite means lighter than super light I suppose. This one again proved WM's top quality.

"Amazing sleeping bag!" 12/24/11

The Western Mountaineering UltraLite 20 degree down sleeping bag is one of the best available. The bag is very breathable (but still water repelling) and warms you up as soon as you get in (and truly maintains the temperature rating given to the bag).Not only is the bag super lightweight, but it also compresses to nothing. While the bag comes with a stuff sack, I use the Sea to Summit eVent XS (6L) compression sack, bag's compressed size is 6" x 7" (reg. bag).Do not let the price of this sleeping bag fool you. For the quality that you get, it is worth every cent. The down is of the highest quality, the sleeping bag is warm, lightweight, durable, and compact... what more can one ask for?

"Amazing Bag! The best bag ever!" 12/19/11

This bag rocks!! I bought it for a backpacking adventure in Yosemite. Nights in the low 30's, and I was toasty warm. This is the best down bag I've ever owned. Its amazingly light weight and compressible. The temp rating seems very accurate too. And, just to put things in perspective, I am a wimp when it comes to cold weather...I normally FREEZE in any weather that's not in the 80's.

"Worth Every Penny" 12/10/11

After spending countless nights freezing in my old synthetic bag I broke down and bought the UltaLite. I couldn't be happier. I am tall and skinny, and the narrower cut helps keep me warm even down in the mid 20's in the Sierra Nevada's. I would buy a second one in a heartbeat.

"One of the best sleeping bags" 06/15/11

I have used mine for over 8 years.I think it's the best sleeping bag for this temp range and for the money.Light and warm. Choose the length that just fits your height, and you are not carrying any extra weight. This would make the feet warm up fast too.I think they put more dawn near the feet section, so you won't get cold feet when it's cold. It is just an amazing product

"Unparalleled" 04/29/11

Hands down, best ultralight bag on the market. Spent 9 months in Afghanistan living out of one pack, and at 1lbs 13oz this compact bag made sleeping in all conditions bearable. Whether in 130 or 20 degrees, it somehow stays breathable/cool during the summer while keeping you snug as a bug during cold winter months.

"I have no words" 04/18/11

Western Mountaineering makes amazing bags and this is another testament to there legendary quality. I was able to use this bag during the late winter trip up in the San Juan's of Washington. The bag worked fantastic, and kept me warm in 25-35 F nights, with no pad. Because I didn't have a pad I lost of body heat to the ground, so I feel it could have handled down into the 15 range with one. Bottom line this bag is simple and effective and well worth the price.

"Simply... The Best." 02/10/11

Truly an Incredible sleeping bag. Western Moutaineering certainly sets a standard with their bags and this one in particular sets that bar pretty high. Its a little rough spending 400 on a bag but if you use the storage bag that comes with it and take care of it per Western Moutaineerings fabulous guidelines, I dont see any reason you couldnt have this bag for 20+ years.
