Few years ago I bought another Under Armour ColdGear Shirt which was perfect for running in low temperatures and I hoped this purchase would be equally satisfying. Unfortunately, it's not the case. The material seems to be of good quality and the shirt fits well but it's not warm enough for CG in my opinion. It's better for early autumn/late spring.
I'm not a fan of hats but this one has been really handy especially when it's cold and rains. I was worried I could get too hot and sweaty after running for a long time but that hasn't been the case. Highly recommend.
