Why We Like The UltraLite Sleeping Bag
The Western Mountaineering UltraLite Sleeping Bag lives up to its name by keeping our backpacks light while still packing in a hefty dose of premium 850-fill down for those chilly nights. A soft taffeta lining caresses trail-weary skin and, thanks to the ExtremeLite shell's breathability, the climate inside of the bag stays comfortable on balmier nights.

New into backpacking, I had a not so great sleeping bag which wasn’t warm at all when it was 40F outside and super windy, I didn’t want to be cold again. I did a lot of research and narrowed it down to this bag and I’m so glad I invested in such a quality product! I stayed so warm in 28F with minimal layers on like a warm cozy cocoon. Love that this is made in America by one single person! Don’t hesitate to invest in this sleeping bag you won’t regret it! I wish they had this in a dog version so I can match with my pup.

Lives up to the hype

It feels kind of pointless to write another 5 star review of this bag. But it lives up to the hype. Very warm, well made, light, packable, very puffy, comfy and made in the good ol' USA.

I never thought i would get used to a mummy bag but I did, especially when it got cold. 20 degrees out and I was roasty toasty in my ultra light western mountaineering sleeping bag. Seriously, when everyone got up and crawled out of their tents someone said he was freezing all night long, another agreed then looked at me and the other guy. I said I was warm as could be and the other said he was ok but put another shirt on. Then he said I must have had a load a clothes on too. I said nope, just my shorts thats it. It really did hit 20 degrees around 5:30 am and I was absolutely comfortable tucked into my bag. I was wonderfully warm. Hearing how the others were not so warm and miserable I felt really good about doing cold weather hiking with my choice of sleeping bags. It,s warm, very lite weight and stuffs down darn near to about a football size.

Best sleeping bag so far! Perfect for 3 seasons and super lightweight. Does not come with compression bag, but that is an easy fix! 11l compression bag fits perfect!

This bag is the perfect mix of warm and lightweight for 3-4 season sleeping. There is simply nothing bad about this bag. WM is the best.
