These shirts are amazing! I initially bought them to wear as undershirts, but quickly realized how wonderful they were to workout in. Had to purchase more and in different colors. Up to nine now that I own. Highly recommended! All purpose shirt for a reasonable cost.

Another great UA product. Durable, comfortable, and breathable. I’d like to see a few additional color versions such as traditional green, purple, etc.

I like this line and the vented style helps me cool down fast. The material seems to snag easier than the other tech styles.

The shirt was for my son. He likes the style, color, quality and the comfort in hot weather. It was a back to school purchase. Very satisfied with quality and style. I highly recommend and will be back for a few more.

Comfortable, Breathable, and Great Fit

Originally posted on Under Armour

This Under Armour shirt quickly became one of my favorites. The fabric is lightweight, soft, and wicks away sweat really well, which makes it perfect for workouts, golf, or just casual wear. It has a nice athletic fit—not too tight, but not baggy either—and the stretch makes it super comfortable to move in. It also washes up great without shrinking or fading. The quality is exactly what you expect from Under Armour: durable, stylish, and built for performance. Definitely worth the price if you’re looking for a shirt that looks good and holds up through tough activity.
