Not Warm

I bought ua base layer 4.0 because it says it will keep you warm down below zero!! I put on the pants and shirt 4.0 and put on a t shirt and overalls. The temperature outside was 45 so I thought I should be ok. Boy was I wrong!!! I could only stay out there hunting for two hours. I was freezing and not enjoying the hunt. I could have bought 5-6 sets of cheaper base layers for what I paid for these!! I will never spend my money for under armor products again. Under armor does not work as described by manufacturer, so buy cheap base layers since you have to wear a bunch of clothes to stay warm!!! Don’t waste your money on these!!!!

4.0 Coldgear Is 5 Stars

South Carolina experienced extreme cold weather this winter, but while wearing my 4.0 crewneck, the cold weather did not phase me not one bit. I see why the athletes opt for this gear during cold weather games.
