This compression shirt keeps you cool and has the right compression in the chest and stomach area. The arms holes are wide so that there is no scratch and overstretching while you exercise.

Just the right amount of compression and this incredible OG Compression material keeps you cool in the extreme warm temps and warm in cooler temps. I would recommend incorporating this OG material to leggings as well. Iso Chill works well but appears has been discontinued. This would be a great substitute.

I feel like it would look so much better if the UA logo was there instead, other than that this is a great mock neck muscle shirt! ... Awesome Mock Neck Sleeveless Muscle

I love that Under Armour brought back their original compression fabric, it feels soft and conforms to the body nicely. The mock neck hugs your neck comfortably and adds a nice aesthetic touch. The shirt fits really well and looks good. The only thing I would like to see changed with the design is if Under Armour would move their logo from the neck to the front left chest area like their other shirts. I feel like it would look so much better if the UA logo was there instead, other than that this is a great mock neck muscle shirt! Looking forward to getting this shirt in more colors!

Under armor always means to me quality products. Got the gear and couldn ’ t be happier. Shirt is comfortable and breathable. Helps me keep my body in check getting older skin is much loser. The shirt keeps it much tighter feels much better.

UA has the only compression shirts in a range of colors and that effectively whisk sweat while not interfering with the workout. 10/10.

The OG feels a bit more compressive but is a bit less comfortable. This is a good color for running safely.

The OG style is absolutely amazing. The fabric is way better than my previous UA shirts and I hope they don ’ t do away with it anytime soon. I got the crop top for indoor cycling, but I ’ ll probably wear it as an extra layer under my bike jersey as the temperature warms up or at the gym.
