We're bringing you this product at the lowest price allowed by the manufacturer so you won't find it cheaper anywhere else. This also means we can't apply any further discounts or promotions.

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'!).

There are few things worse than panty lines that peek through your breeches while you’re trying to ride. The Under Armour Pure Stretch Thong features an unfinished hem that not only stays put, it creates a smooth silhouette undetectable even under the tightest breeches. So if you’re looking for in-your-face performance with a sleek no-show design, the Pure Stretch Thong is your new secret weapon.

The fundamentals
•Fitted: Sits close to the skin for a streamlined fit without the squeeze of compression.
•Super-soft stretch fabric delivers excellent all-day comfort for any activity
•Laser cut edges offer a hem-free construction for a smoother, more flattering silhouette
•Lightweight, 4-Way Stretch fabrication improves range of motion and dries faster
•Anti-microbial technology keeps your gear fresher, longer
•Exposed back ensures a seamless look even under UA Compression
•Tagless construction and cotton gusset offer superior comfort and peace of mind

    Under Armour Pure Stretch Thong is rated 3.0 out of 5 by 4.
    Rated 1 out of 5 by from Terrible for riding- equally bad for walking. I mistakenly bought 3 pairs that will now sit in a drawer until I throw them out. No one should even think of trying these to ride in. There is nothing to keep them from sliding around, leaving you in full contact with your breeches...

    Rated 4 out of 5 by from Invisible Under Breeches These fit great and really do look and feel invisible under beige breeches. Perfect even under low rise breeches. In fact, I like these so much that I also wear them under summer weight dresses because they don't show through. The only complaint I have is that the cotton crotch is not sewn in at the top and rolls down a bit. It would be simple for Under Armour to fix this little issue.

    Rated 5 out of 5 by from Great for riding! I found these to be very comfortable for riding! I did not have the experience of the other reviewer. They were a tad tight at first, but after I wore them once or twice they were perfect. Ordered another pair!

    Rated 2 out of 5 by from Not one size fits most. I was so excited to find this Under Armour Thong. I wore it once. It felt like tissue paper that just rolled into a bunch on the side when I pulled my breeches up. I will now wear them again.

    I started riding when I was 9 years old and quickly got swept up into the competitive hunter/jumper world. I showed my first pony, Chloe, in the Small Pony Hunter divisions were we competed at shows like Fairfield Hunt Club, Old Salem, HITS, and West...
