    Under Armour UA Tech Shortsleeve Tee is rated 4.8 out of 5 by 46.
    Rated 5 out of 5 by from Love this shirt! This is a great shirt to wear to riding in or to wear out and about. Great fit, great cut.

    Rated 5 out of 5 by from Great shirt! It was exactly what I expected! Nice and cool for the summer!

    Rated 5 out of 5 by from Keeps Me Cool! I bought three of these tees for the summer and I love them! They keep me cool even in 90 degree temperatures. Just what I was looking for this summer! They are also very comfortable. I love the Armour line and I am so glad Smartpak always carries this line in summer and winter. They are not fitted so if you are looking for that, they probably won't work for you.

    Rated 3 out of 5 by from Cute but hot Bought two of these shirts. They're great for under 80 degree weather, or breezy hot weather when very sweaty or if the shirt is wet. Just not very breathable, but nice quality and fit.

    Rated 5 out of 5 by from Nice, cool shirt I love under armor so it was a surprise to find it on smartpak! I always ride in their heat gear shirts because in south Florida you will do anything to keep cool when riding in the hot and humid weather! This shirt does just that. Only down fall: it runs a little big.

    Rated 4 out of 5 by from Love these shirts! I ordered the Orange and the mint color in medium. The fabric is so comfortable. I have worn them both all day in the heat and dirt and felt so fresh at the end of the day. The fit is on the loose side which is fine and comfortable, just the photo makes it look more fitted. My only complaint is the v neck is low if you're looking for sun protection...you will need sunscreen or a bandana/ scarf type thing in front. A crew neck option would be great since these are obviously made for hot weather.

    Rated 5 out of 5 by from Great features. Love this shirt. Great for hot weather riding. Washes wonderfully and wears great.

    Rated 5 out of 5 by from Fitted but not clingy I have had this shirt for over a year now and wear it weekly. The fabric still looks amazing and is very breathable. Living in Texas, I deal with a high amount of heat & humidity, so I love how comfortable this shirt is! I am a size 14 and the extra large fits loose enough to be comfortable without being too clingy. I would definitely recommend this shirt! I wish there were more colors :)

    Rated 5 out of 5 by from Great fit and it keeps me cool I purchased three of these shirts thus far -- two in black and one in aubergine. They are light and extremely comfortable...and skim the body but are not revealing. Just perfect for riding and an excellent value for the price.

    Rated 1 out of 5 by from way baggie The description said the shirt was fitted. I ordered my usual size and this is way too big and baggie. The material also was flimsy. It will go to Goodwill.

    Rated 4 out of 5 by from Nice Barn Shirt! I have several of these now and they do help wick heat and moisture away from you. The material also stays relatively clean so I don't come back from the barn filthy. They are not very fitted though.

    Rated 4 out of 5 by from Stay cool under pressure! I had gotten some Under Armour shirts like this for running and decided to get a few more for riding. Very cute with the SmartPak logo included. Very lightweight and cool. They should be fitted but I got a size too big and am slightly disappointed in the fit. Would buy more and need the cooler weather version now!
    Date published: 2014-11-06
    Rated 5 out of 5 by from Fabulous! I bought this about half way through the summer as I had heard of how fabulous they are for riding in. I didn't expect the material to make such huge difference, but I rode 4 horses in 90°F (and I'm a huge sweater) and before long my shirt was completely dry and didn't feel gross at all. The fit is great

    Rated 5 out of 5 by from Love this shirt! This is a great, light-weight shirt and a terrific value for an Under Armour piece. Love the vibrant colors--wish there were more!

    Rated 5 out of 5 by from Great shirt Bought this shirt for the hot humid weather in NC-loved it so much ordered 2 more! Really helps keep you cool and wicks moisture
    Date published: 2014-08-08
    Rated 5 out of 5 by from More colors please! This is the best shirt in existence. I think I sweat more than the average person should, so I was excited but skeptical to try this out. Not only does it keep me cooler, but it also gives the appearance of being cooler - no more looking I'd just run a marathon while teaching lessons! Smartpak, it's a great product - can you please produce it in more colors? And, a collared polo shirt would be a must-have in my closet. You can't beat the price.

    Rated 5 out of 5 by from Must have for a southern summer This shirt is great for the muggy summer days. Soft and comfortable fabric that doesn't stay soaked with sweat. The semi-fitting cut shows off curves without being tight. It does run large so if you are between sizes, definitely size down. I just wish it came in red.

    Rated 5 out of 5 by from flattering fit Worn once so I can't speak to the durability...but I love the way I look in the Medium. I am 5'6" 160 lbs. Fabric is cool, comfortable, and light.

    Rated 4 out of 5 by from Great Love it for summer riding and i LOVE LOVE LOVE the SmartPak logo on the sleeve! Would give it 5 stars but it isn't that flattering. But for those days when its hot ill be wearing it anyway!

    Rated 5 out of 5 by from Best summer riding schooling shirt!! I had been looking for summer riding shirts for a while -Then I tried Under Armour and I went back and bought one in every color! Lightweight and cooling, the medium fits perfectly (I am a 36 C) without being clingy at all. I highly recommend this shirt
    Date published: 2014-07-11
    Rated 4 out of 5 by from Nice shirt, runs a bit big! I got this shirt in the "Exotic Bloom" - yes, I was sucked in by the fancy name and the almost metallic looking color in the photo - in reality it's not metallic at all but just a nice pinky lilac color. It is a very comfy shirt, I have ridden in it in 90+ degrees with heat indices in the upper 90s, and it's very light and breathable. I got the large which unfortunately was a bit big on me... I definitely want more - next time I will get a Medium... in "Pride".... ooooh! Swanky!

    Rated 4 out of 5 by from Nice shirt Nice shirt. Not as fitted as I was hoping...I maybe could have gone a size smaller. I ordered the pink one and it's more orange than pink. Long enough in the back for coverage in the saddle. I like the material too. I stayed nice a cool on a long ride in the hot sun.
    Date published: 2014-06-30
    Rated 5 out of 5 by from fits perfect! I have to agree with everyone else. This shirt fits perfectly, it sits nicely at the hips and is shaped to enhance the female figure, but it's not too small and not too large. Plus it has the Smartpak logo on the sleeve for extra coolness! It is lovely and comfy in the hot weather and the V-neck is super attractive. I originally bought the black and then came back for all the other colors. I don't usually give reviews unless I feel very strongly about a product.
