Best workout T ever

These shirts are hands down the best workout tops I have ever worn. I find the extra arm/shoulder cut outs more comfortable than a singlet top and the material lets me sweat naturally. I am broad across shoulders and chest and I find this top fits there without turning into a billowing tent around my stomach. After my first I quickly bought two more

Solid/strong sleeveless shirt

While I prefer true-tanks, this sleeveless muscle top is first-rate. Comfortable/breathable material, subtle logo design, and the sizing/fit is accurate.

Perfect workout shirt

This shirt fits comfortably and breathes great! Perfect for working out or as an under shirt for polos or other shirts. [This review was collected as part of a promotion.]

Awsome Tank Top with great features

what can I say but the fit is great and the material is first class and looks great the bold logo really stands out and gives the shirt excellent style and the features really do their job. the material wicks out the sweat and dries before your eyes. I bought fur oof the UA shirts and two compression leggings the fit and feel is superior to any others I had. Great Job UA [This review was collected as part of a promotion.]

Lightweight Workout staple

The lightweight material is perfect for gym workouts. [This review was collected as part of a promotion.]

Great Workout Shirt

I loved the old charged cotton sleeveless shirts, and this one may be even better. It's very light and moves with you instead of either sticking to you or falling off during workouts. I am very impressed and will definitely buy more to replace my older tops. Sizing is right on point like most other UA products.

Great Product for a Workout and/or a WalkAbout

This is one of the most comfortable, dependable muscle tanks that I wear now. I will definitely order more of these well-made, durable tanks. Sizing was just right for me as a Medium.
