My best friend swears by it. It's all he'll use. I thought it was just him being him but I invested in the compression top and bottom in realtreeAP. Got it on ebay pretty reasonably priced because its not the most current pattern. I watched my buddy walk into the 15 degree winter weather in just his base layer (under armour), hoodie (under armour), and pants. and he sat there longer than I could. I really like mine. Im sure there are better options for the price (smart wools, etc.) but I really enjoy my under armour. My only complaint is that often times if the weather is above 60, I will wear my camo cargo pants and my UA compression top. It makes me sweat a lot walking in to the stand and then I feel wet the rest of the sit. But in colder weather I don't have that issue. I would recommend at least trying the top from ebay.
