I’d like to review this product but it’s been 3 weeks since my order was placed and still haven’t received my gear. I have been in contact with UA and they don’t know where my order is either.

This shirt feels good when I move in it and I really like the shade of red it came in. It’s also the type of shirt you can wear while walking around the city in the summer.

This shirt is perfect for my baseball players to wear under their uniforms for cold games. They like the tighter fit. It doesn’t interfere with their movement on the field.

Best Base Layer for Cycling
Originally posted on Under Armour
Yes, I recommend this
I reloaded my inventory for the base layer I use for all of my cycling rides. Wicks sweat away easily, and it is effective in hot Florida weather. I also like the variety of colors, which is great for multiple kits. The fit is true to size and can be washed and dried without dulling colors or shrinking from original size.

Definitely compressive!
Originally posted on Under Armour

The fit is as advertised. It is very compressive but not so you feel like you're being squeezed by a boa constrictor. It's very breathable and wicks away moisture very well. It also provides support for my back, something I didn't really consider when purchasing it.

Perfect fit!
