About this style

This thermal baselayer top offers warmth for cold weather training and activities like snowboard sessions with a practical design. Cut to a slim fit with a funnel neck, this long sleeve lightweight shirt features dual-layer performance fabric that keeps you warm while drawing moisture away from the skin. The brushed interior adds comfort, while the streamlined armour design prevents bulk and stays in place as you move.

Beyond warm. Ran in the snow. Did 6 miles and was very warm. Soon as I stopped was sweating endlessly

Weird smell

Originally posted on Under Armour

Yes, I recommend this

I have the black color and it is great shirt but for some reason this shirt has a strong vinegar smell to it. Do not know if I should wash it or just return it.

Fits well, easy to clean

This gear fits snug in the neck, and slightly looser than compression elsewhere. Best bet is to hang dry after washing.

cold gear top

Originally posted on Under Armour

Yes, I recommend this

This is very warm. My family and I love this cold gear. The neck is a little small, so you might want to go up a size to go over your head. They wash really well and hold up.

Never liked either “turtle necks” or right form fitting clothing but this is comfortable and adds a nice layer for working outdoors.
