I’ve only had the short-sleeved shirts in the past. I’m gettin back into body-building and the added compression from the long-sleeved version makes a BIG difference. I’m glad you brought back the OG, original gear. I can’t wait to try them!!

This is my go to base layer. Wether its a little cool out or blazing sunny summer, it blocks UV and lets me golf freely.

I’ve bought probably 10+ of these at this point and they are top quality in my opinion. I wear them everytime I golf for the compression and sweat absorption. Very good at blocking the sun and keeping cool on a hot day

Soft, light but durable.

Wicks sweet greatly, soft, light, doesn't make you feel the tightness while protecting from burns.

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!

Compression Top

Originally posted on Under Armour

Yes, I recommend this

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.

Great material but too snuggle for me

Originally posted on Under Armour

Yes, I recommend this

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