Accomplished first test

I've just used this sleeping bag twice so far, but one of them was a night under the stars in -20F/-29C temperature. It held me warm through the night thanks to the two good drawstrings over the hood and around the neck.

The bag is very light and seems durable. However, I miss a better compression bag for this price. I will therefore buy a smaller compression bag to be able to compress it even more.

All in all, I'm happy with my new sleeping bag and look forward to feel the reduced weight compared to my old one on future winter expeditions.

Toasty

There is no doubt you will stay toasty warm in this sleeping bag. I didn't even need to sleep with my socks on! My feet were so warm I needed to use the other side of the zipper just to stick one foot out cause I was a little to warm. I can't wait to get to use this for some winter camping up near lake superior. That will be the real challange
