I swear by UNDERARMOUR HEAT GEAR. It keeps me drier, cooler and more comfortable in the hot summer months. The material beathes very well.

5 stars, even though I like the 511 shirts better. They have flat seams.

Being a female, the tightness is excellent, holds everything where it needs to be :0) and keeps you cool as a cucumber. I reside in central Florida and cannot even begin to think about wearing a cotton t-shirt under my vest. (I used to until I discovered this product) I would reccomend this product to anyone who wears body armour!

Yes it keeps you cool I just feel restricted you know it feels real tight....

This is like a second skin, it moves with you unlike regular T's!

This type of undershirt is the best and i will never go back to regular cotton! It last alot longer and is more durable than cotton. It costs a little more... but it is well worth it!

I have tried the other brands like C9 from target and it just does not work as good as the Under Armour. Very much worth the extra money!

I own like four pair of these. two short sleeve and two long sleeve and even though they are a little tight when you first put them on, after wearing them for a little bit it's almost as if you forget that you're even wearing it.

The only thing I will ever wear under a vest since I tried it.... It makes a difference you notice the first hour

comfort is a must, and this under armor shirt you will notice the difference right away.

I use it under my uniform as well, as using it for when I work out. It's nice because it holds things in place, being female and all.

This is a great product to wear under your vest. I prefer the 5.11 series , but this is also great shirt.

good shirt but it takes some getting used to. It does keep you cool.

these shirts are great!

soo lite! and they dry quickly

Light weight, drys fast and wicks the moisture away from your body. Great for wearing under your vest...

Great Product I have been using under armour for years now and I rarely use cotton under shirts any more these provide so much more comfort

Firm fan of this product.

Good product.

for me its between this and th e5.11 shirts i like the feel of both and puttin both through the courses right now to see which one last longer....i do like the mes under arms of the 5.11 allows alot more breathability

i wore this stuff when I was a uniformed officer and I tell you it feels good !!!

Greatest stuff ever made

I wear one almost everyday at work.

It's an everyday apparel for me very comfortable.....

I wear some form of heat gear everyday. This is the best product Under Armour could ever make. Won't go to work without it under my vest.

love them I need more
