We're bringing you this product at the lowest price allowed by the manufacturer. That means this item isn't eligible for additional discounts or promotions.
We're sorry, but certain colors/sizes are sold out and are no longer available.

As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Why We Love This

The same soft-feeling, sweat-wicking, odor-blocking, light-weight fabric of the UA Tech Shortsleeve Tee, but in a long-sleeve zip version for easy layering and protection against sun and wind. Plus, it's packed with all the Under Armour performance you know and love. Imported.

Favorite Features

  • Super-soft UA Tech™ fabric delivers hardcore UA performance with soft, natural feel for all-day comfort
  • Signature Moisture Transport System wicks sweat to keep you dry and light
  • Raglan sleeves unlock mobility for serious range of motion
  • Rolled forward flatlock seams with ruching detail adds a feminine touch
  • Drop-tail hem offers superior back coverage
  • Stand collar with 1/4 zip front and zipper garage is easy to take on and off and prevents chafing
  • UA Heatseal logo at bottom left hem, SmartPak logo behind the collar & on left shoulder 
  • 100% Polyester

Sizing it up

    Under Armour UA Tech 1/4 Zip is rated 4.8571 out of 5 by 14.
    Rated 5 out of 5 by from Great layering item Perfect to wear under a vest for cooler days, but also thin/light enough to wear on a sunnier day and not get sunburnt on my arms. Comfortable fit, collar can stand up or fold over. Good arm length (I'm 5'11"). Dust and hay didn't seem to stick to it at the horseshow.

    Rated 5 out of 5 by from Comfortable and classic! I was hesitant to order this as a summer riding option, but I am so glad that I gave it a chance! It has become my favorite riding shirt for those spring and summer early mornings and even for the cooler nights. It is lightweight and super breathable. It is a must for shows with its versatility and classic styling.

    Rated 5 out of 5 by from Great layering shirt I love these shirts for layering year-round. I now have three of them. I wear them over short sleeves on cool spring, summer and fall days/nights and under heavier layers during the winter. The material allows you to move without binding so I can ride my horse or work around the barn in comfort. The large is a perfect fit for my 5'11", 148 lb frame and longer arms.

    Rated 5 out of 5 by from My 2nd one I bought a second shirt because I liked the first so much. This time I wanted to try the XL and I like the little extra room it has. I usually layer in winter, so the XL is more comfortable for another layer under it. Love the zipper -- gives me the choice of covering my neck or not.

    Rated 5 out of 5 by from Great between seasons shirt I have only worn this shirt twice so far but it feels great and is the right weight for layering or inbetween the seasons. Washed well, but I hung it up to dry. Seems to run a little small. Nice fabric and stays tucked into breeches.

    Rated 5 out of 5 by from Great Shirt! I bought this as a gift for my daughter and it has quickly become a staple in her winter riding wardrobe. It fits true to size, is quite flattering and she loves the style and warmth. I ended up purchasing the purple color as well.

    Ever since I was the girl with 1,000 breyer horses and the raggity braid in her hair, I was always obsessed. In second grade I moved into a town with a barn right down the street, which is when I started taking lessons...
