We all hate it. That stiff, distracted feeling you get when you're out in the cold. That's why, we built a baselayer that keeps you warm and dry without being bulky or riding up, so you can stay focused all season long.

Great cold weather gear
Originally posted on Under Armour
Yes, I recommend this
I bought this because I was about to embark on a cold winter vacation to watch my son play college baseball. The garment was excellent and it did what I expected it to do and that was to keep me from freezing. It served a purpose better than thermal underwear.

I live in this cold gear when up in the northern climates. It makes the best under garment for the outside, and an excellent base garment for the inside. Outstanding as a night shirt, too!!

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!

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.

Weird smell

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.

Wonderful layer piece for golf and outdoor activities. Neck is a bit sloppy

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.
