Nice Starter Bag
I just got the bag Wednesday, and used it Friday and Saturday for a weekend climbing trip. The weather sucked in WI, with rain (some of it freezing) and wind. Never ended up climbing, but this bag was my go to for a nap and night time. It's not too tight of a mummy cut, with some wiggle room, which is good for me because I move quite a bit at night. Used Thermarest Prolite sleeping pad to stay off the ground and the combination of the bag, the pad, and a light insulating layer of clothing and some wool socks kept me warm all through the 35 degree nights. I am a cold sleeper, so I didn't mind seeing my breath in the tent...and the bag did it's job. I say its a true 40 degree bag. It's pretty light for the price, compresses small--I fit it in a Sea-to-Summit eVent Compression Sac and used the size small which worked perfectly. I'm very happy with the bag after it's initial use, and definitely recommend for starters or broke college students like myself. The bag was tested in some nasty weather--cold and rainy--but I couldn't wait to crawl inside it the second night. Treat it right and it will last a while too. I got my money's worth.
