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.

Great base layer or stand alone

Originally posted on Under Armour

I ordered this to wear under a flannel, specifically during colder weather. I wasn’t disappointed. It’s a great base layer, keeping me warm and looks great, especially if you like the turtleneck look. It also looks great on its own! This is a fitted shirt, so unlike the compression shirt, it’s not too tight, but just enough to give you a sleek look!

Great base layer

I used this shirt under my wind shirt on cooler morning golf, and it performs as advertised. It keeps me warm without restricting my movements and doesn't feel damp like other garments I've used.

Best Cold Gear Mock ever

Originally posted on Under Armour

Yes, I recommend this

This mock is not too heavy, not too light, just right. It does not bunch up or constrict me when I am playing golf. Paired with a light sweater I was more than comfortable all day long in 55 degree temps. I am very happy with this purchase.

Shirt is warm and is built with looser fit rather than compression it.

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

Originally posted on Under Armour

Yes, I recommend this

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.
