Light and tinyReview by Dave
This is a very comfortable bag and a joy to sleep in. I've had mine for 20 years. I still get a kick out of showing friends how tiny it is when it's and I have stuff sack. Worst thing about is that it's hard to get up and out for an early start in the morning. (Posted on 8/2/2017)
Best In ClassReview by Bill
I purchased this bag from the Seattle Feathered Friends store in the early 1980’s and used it in the Wash. Cascade and Olympic Mountains for more than 20 years in all weather and seasons with zero complaints. It’s been passed on to my daughter who used it two years at Mount Rainier National Park, several years in Bend, Oregon, and many trips to California National Parks. Take care of the bag and enjoy many, many years of reliable performance. Can't ask for more from a sleeping bag. (Posted on 6/4/2016)
