NF Lightlewrote a review of MontBell U.L. Spiral Hugger #1 Sleeping Bag: 15 Degree Down on December 5, 2012
Familiarity: I've put it through the wringer
I've owned this bag for over 4 yr.s and it still amazes me. I've thrown everything at this bag from the Tetons and SW Yellowstone to the OP (Olympic Peninsula), Blues, Rockies and Salmon breaks. I hunt w/ it, camp w/ it, river raft w/ it, and it keeps on truckin. Yes it's rated to 15 deg. but honestly, with a lt wt liner and some wool socks I've slept like a dog down to 0 degr.. I use a therma rest trail pad and that's it. Last trip out, it rained INSIDE my tent for 2 days straight (day 2 it rained over 4" in less than 24 hr.s), and though the outside of the bag got wet, I was dry and toasty, and again singing the praises of this bag on the inside. I was concerned about the durability of this bag when I bought it, but not since. Also, I sleep like an epileptic in electro shock therapy and this bag stretches like a slinky and still keeps me warm without constricting my spastic parts. Honestly, I've never tried the Marmot or W. Mtneering bags, but why would I?? This bag is Uber lt, WP, 5 different kinds of comfy and keeps me warm w/out making me sweat. I'm constantly looking for better/lighter gear- just not sleeping bags. This is THE ONE!
