Still The Amazing Bag I Know And Love

I have borrowed this bag from my dad for a number of trips and I finally invested in one for my wife (sleeps cold) for 2 weeks in the andies. First speaking of my dad’s experience: he’s had this bag for over 15 years, and slept in it more than 100 nights outside of a tent in alpine temperatures ranging from 10-50 degrees, and never had an issue with it. Still lofts like the one I just bought. My wife’s experience sleeping in 15+/- in the Andies: kept her warm enough and very cozy. The only drawback you can come up with for this bag is the price, but at the end of the day you will get what you pay for. When you’re ready to buy your last sleeping bag, buy this one.

The Cadillac Of Sleeping Bags

Both incredibly light and warm, this bag DELIVERS. The only complaint I have is that the bag is a big tight in the feet and knees however that is by design to lock in warmth. Used this bag in low 30s with nothing but a t-shirt and underwear and stayed toasty warm.

Western Mountaineering Hits Another Home Run

I have a WM zero degree bag and 30 degree bag, but I feel the cold more now that I am nearing age 70. The 20 degree bag hits the sweet spot for cold nights, packability and versatility. As always, WM quality is unsurpassed.
