Does anyone have any experience with Sierra Designs Nitro bags? They seem expensive--does their quality justify the price?
I really like to be warm at night. The intended conditions would be 25F+, under a tarp, sometimes in a hammock, using any permutation of the bag with a Ridgerest, Prolite 3, REI Travel Down, down throw, and/or GI Poncho Liner. The poncho liner is my underquilt.
