My 8 yo and I spent the weekend at the Red River Gorge in Ky. He slept in his ENO rig and I slept in my double layer camper fom BIAS. The low temp was 50f approx. I was super warm and comfortable. Any input on how much further I can push my wallyworld waffle pad and his Eno Ember would be appreciated. Please view photos in my gallery. I have not mastered including them in post.
