My brand new neoair xtherm went flat TWICE in one night on my first snow camping trip. I started off with the pad inflated TAUGHT (as in as full as I can get it) at 4:30pm. It was dark and I was in bed by 5:45pm. By 9:45pm I was freezing because the pad was half empty and I was on the ground. I reinflated to TAUGHT and slept well until i awoke freezing on the ground with the pad half inflated. I could not tell you when this happened, but I estimatebefore 5am. I roughed it and did not bother reinflating again.
The outside temps were in the teens (F) and at worst in the high single digets. I was in a single wall/floored tent with a footprint. I packed out/shoveled a base so I was on ~6″ snow over dirt. in my living room (70*F) the pad goes from TAUGHT to still acceptably inflated but noticeably less taught over night.
Is my pad leaking or is the cold air just causing my PSI to drop through the literal floor? Would a CCF pad underneath fix this? Return the pad? I have never had this problem with self inflating OCF pads…
