Does anyone have any experience with this stuff for hunting. Both the light weight or thermal tyes. I bought some Under Armor heavy bottoms for colder hunting and some of the lighter weight stuff (Polar Tec maybe?) at Cabelas. I was impressed how good the UA fit (for a big guy 300#) I fit into a pair of XL tall and they were very comfortable. The other fit different (looser) but still felt pretty good. they are a bit costly so I hope they work well.

Any info would be helpful.
