Last season, we camped in Montana. The weather was in the low 30s during the day. Pretty cold at night. I had a 4 season tent, klymit insulated mat, and a loco libre 10° down quilt. Everything seemed fine expect the damn mat. That thing sucked. I kept sliding off of a body part would fall off and be on the ground till I work up from that body part being numb. I see you can by a wider klymit insulated mat but what are other options? Sleeping pad under my current mat, wider mat, different brand? How can I fix this?
