This product is great. Nice compression fit sleeves. Wall designed and well-made. My son is wearing as a light thermal under baseball jersey.

Compression shirt

Originally posted on Under Armour

These compression shirts are excellent quality. I bought this for my grandson who uses it for football practice. He likes a snug fit to sweat in.

There's no surprises with this heat gear... form-fitting, moisture wicking, and washes easily with no fuss. Couldn't be happier!

I have several colors and would love for UA to make orange and sky blue with the matching leggings. A very comfortable piece of clothing. Whether you are walking, running or bike riding this UA product works. It washes well and does not lise shape like other brands.

Very snug, but comfortable fit. Stitching seems to be holding up very well.

The product has a nice feel to the material, but it fitted smaller than my previous large compression gear. Had to return it.

Love my Under Armour compression shirt

Originally posted on Under Armour

From my experience, Under Armour has the best compression shirt. Other brands have compression shirts, but UA ones last longer and stay in the compression form much longer. I continuously buy different colors and lengths since I wear UA compression shirts to the gym most days.

Soft, Stretchy & Comfortable

I bought this for my husband to wear during the cold months under his work shirts. He wears a Large normally but prefers these shirts to be snug fitting, so I bought this in a Medium. He loves the feel of the material and the excellent feel and comfort. We both love Under Armour attire and accessories. Under Armour closely fits our clothing style. Thanks!!

A comfortable wear

One would think that being a compression shirt it would feel too tight and uncomfortable. However, I found the shirt, after wearing it all day outside being active with the granddaughter, very comfortable. As you can see, I wore it while engaging in various activities throughout the day.

This compression tee is super light weight. It has veneration on the side and a cool logo on the front. It does run quite small but overall super great quality and stretch.

Comfortable fit and keeps you cool on hot days. I use this as an under layer when playing golf or for my weekly workouts. Works better than advertised!
