I'm not sure I'd advise any kind of mat for use in a tree-stand. In the other thread on this topic I suggested ways to keep your feet off the ground to eliminate the heat-sink issue. In a tree stand anything you add to the standing surface could potentially cause your footing to be less than optimum...Let's face it, when you're up in the air your footing is already subject to second guessing. In a tree stand I usually tough it out...although in the pre-dawn dark, when I can't see anything, I have been known to wrap an extra sweatshirt from my day pack around my booted feet.
