I packed this bag for my recent Colorado elk hunt. Super light and compact. Kept me warm through the night.

Got to try it out
Review by Nathan S. on 1 Apr 2026 review stating Got to try it out
Got to try it out a couple of times during deer season. Very warm in 20’s & 30’s. Definitely a good addition to my deerstand sitting all day.

Great sleeping bag option.
Review by Steven B. on 21 Mar 2026 review stating Great sleeping bag option.
I purchased this specifically for a hog hunting trip with the plan to sleep inside the back of the truck with an outside air temperature of 50F. I never once got cold and the option to walk around with the sleeping bag still on and open arm zippers really helps you maintain an optimal core temperature. It’s extremely light weight and compresses down very well for packing in and out. Thanks for creating such a unique and usable product.

Love it
Review by Matt L. on 21 Oct 2025 review stating Love it
Great bag. Really liked how it preformed in the field. Bit tight but the arm holes fixed that. Slept in my layers and had a great night sleep
