bringing this one back up. I tried my sea to summit insulated mat again this yr, and it just isn't getting it done for me. Slept terrible, and its not a problem with the bag because im in the WM Badger, and it was plenty warm. For me, its a slip and slide issue with the matt, and then I get sore hips because im a side sleeper and can never seem to get comfortable for any period of time. I tossed and turned all night, and finnaly fell asleep around 4 am for a few hours. This is a huge problem because then its daylight when I wake up, and im not out as early as I need to be for the morning hunt. Thinking about trying the exped winterlight pad.
