I try and never sweat on my way to the stand (will walk to the stand with just a t-shirt on and pants with no long johns underneath. However, i love the underarmor, i am one of those new gadget guys that spends $500 to $1000 per year on new stuff that comes out( always a justification for new clothes, gloves hats) but the underarmor i found was the best and warmest layer yet and i tried all types of long johns and thermals. IMO you can't beat it and now that they have the camo its even better.
