About this style

When the weather turns colder, the HeatGear Armour t-shirt from Under Armour is an ideal base layer. It's cut in an easy relaxed silhouette. Pinhole mesh fabric provides breathability without sacrificing warmth, while four-way stretch ensures easy movement. As you start to work up a sweat, quick-drying fibres wick away moisture from your skin. The hem is dropped at the back for good coverage.

Don't like the material or fit

Originally posted on Under Armour

No, I don't recommend this

These shirts have a much tighter fit than the picture. I ordered a size up, and it still was too tight for me. The material is a little scratchy and uncomfortable and slightly see-through. I tried them on with leggings that have a black waistband, and the waistband was easily seen through the shirt. I worry it might get more see-through when wet with sweat. Returned due to disliking the fit and the material.

Hi, there! We're so sorry our shirt was too tight and the material wasn't what you were looking for. We know that when you're not feeling your best in what you're wearing, you can't shine like the MVP you are. We're sure we can find something that makes you feel next-level, like perhaps our UA Vanish Seamless shirt, which offers a looser fit and is made from a different material. I'll send an email to get more details. Talk to you soon!

Love the mesh Heat Gear Shirt

I like the material of Heat Gear shirt. It's so soft stretch and breathable. The only one down side is the shirt is too long for a M size.

After trying my first Heat Gear top I was sold. I now have a closet full of Heat Gear. I can’t wait to see the new line for Fall and Winter. Thank you Under Armor.

Very comfortable and lightweight!

This tee is perfect for running and for everyday casual wear. It is moisture-wicking but also nice enough to just pair with jeans. I have a few colors in both the tee and the tank!

Love this shirt!

This has become my new go to shirt for fitness class, yoga or running errands. I love that it is fitted and not the boxy loose fit. It doesn’t ride up during class and show your midsection. The material is breathable and lightweight. I wish more colors were available. It runs true to size.

I generally wear t-back tanks, but love these short sleeves for tennis for cooler indoor temperatures. Comfortable, light, and great fit. I have a five and would get another if a different color if available, like a lighter blue.
