30F Goose Down Mummy Sleeping Bag by WESTERN MOUNTAINEERING

This is an extremely good ultra light sleeping bag that you will have for many years. Every time I pack this bag up for a trip I am awed by how compact and light this bag is and yet how comfortable in a wide range of temperatures. Very breathable yet also very warm. It's expensive but I expect it to last at least 20 years so I would say it is definitely worth the price. Read more

Great bag. Super light and seems pretty warm. Haven't slept in it below about 40 so far but it was a touch hot in those temps. I think zipped up it will hit just right at 30 and take me down below with pretty good comfort. Read more

I was not able to take this camping until last week, after the 30 day return policy. This IN NO WAY HAS A HEAVY DUTY ZIPPER. It got to below 40 degrees nightly and the zipper broke on the 2nd night just by me rolling over! I had to go sleep in the car. If I was at a higher altitude and did not have a car I could have frozen to death due to this zipper failure. I will try to get my money back as this bad is NOT WORTH $50 let alone $500!!! If this company thinks this is a heavy duty zipper then I have to question the quality of all their products. DO NOT BUY UNLESS YOU ARE WILLING TO RISK YOUR LIFE. Read more

Great bag and very lightweight. It’s expensive but you get what you pay for. Read more
