Familiarity: I've put it through the wringer
I bought this sleeping bag to use for backcountry hunting after my old down bag just wasnât cutting it anymore. The extra space and design of this bag is amazing. Iâm 5,10â 165 and the regular size works for me with a sleeping bag liner. The main reason I went with this bag over other high dollar down bags is because of the extra space it offers and I am a stomach sleeper and need any extra space I can get. I have to leave the zipper down about 4-5â to get my arms above my head but that doesnât bother me because this thing is warm. Iâve slept in it in temperature ranges varying from 10 degrees to 70 and elevations of 4,000 to 11,000 feet without any problems of sweating or being cold. I have it paired with a Nemo tensor 0 sleeping pad, and most nights are spent in a Big Agnes flycreek ul2 and that tent is perfect for 1 person and gear.
In the picture Iâm at around 8,000ft elevation, 2 feet of snow on the ground got down to 15-16 degrees and snowed 5 inches through the night. I was plenty warm and slept good. I am super surprised the tent held up to the snow load because I slept too good and didnât wake up in time to nock it off.
