The sun shirt you'll live in. The Ultra Breathable Short Sleeve Show Shirt is built for riders who refuse to choose between staying cool and looking polished. UPF 50+ protection runs from collar to cuff, perforated panels dump heat exactly where you build it, and the buttery-soft four-way stretch moves with you from warm-up to victory gallop.
Crisp enough for the show ring, easy enough for the barn — and just as at home on the pickleball court, tennis court or golf course. One shirt, every kind of day in the sun.

Store owner replied:
Thank you, Marie-Claude! We're happy you love the colour of your Ultra Breathable Short Sleeve.
Tried my new show shirt on one of the hottest days this year, definitely one of the most breathable shirts I’ve ridden in and felt comfortable all day. Ended up wearing it for all 3 phases (dressage, show jumping and cross country).
Store owner replied:
Thank you, Lindsey! We're delighted the shirt kept you comfortable on such a hot day, right through dressage, show jumping and cross country. We appreciate you sharing how it performed across all three phases.
Our team loves the new shirts with our team log on them! They are such great quality for an amazing price. The design is amazing and we love the breathability of the shirts!
Store owner replied:
Thank you to the UMaine Equestrian Team! We're delighted you love your team-logo shirts and that the design, quality and breathability are working well for you.
This shirt is perfect to wear under your show coat or on its own! The material keeps you super cool and drys super fast! It’s very flattering and simple
Store owner replied:
Thanks, Katelyn! We're glad the short-sleeve shirt works both under your show coat and on its own. We appreciate your feedback on the cool, quick-drying feel and simple, flattering style.
This shirt feels like silk! I’m absolutely obsessed
Store owner replied:
Thank you for the review! I am so glad you love your new shirt!
Material is so soft and light weight! It seems like it would be thin and see through on but nothing shows! The mesh material is nice with the hot weather in the summer, especially with a show jacket. Very satisfied with this product!
Store owner replied:
Thank you, Maddie! We're glad the soft, lightweight fabric gives you the coverage you want and feels comfortable in summer, even under a show jacket.
I love this show shirt so much!! It’s incredibly breathable and lightweight, butter soft and such cute color ways!! I bought 2 for this show season… thinking I will definitely need to buy a couple more!! So easy to wash too, they clean up so nice!
Store owner replied:
Thank you, Ruby! We're delighted you love the soft, breathable shirts and their colour options. It's great to hear they wash up well through show season, too.
No shirt has been as breathable and as cooling as this one
Store owner replied:
Thanks, Shawn! It's wonderful to hear your customers are enjoying ARMATEQ. We appreciate you sharing their enthusiasm!
I was pleasantly surprised by this shirt! I bought it mainly for the color, not really expecting the material to be any different than any of the million different sunshirts I have from assorted brands (I have the gamut of high to low end and am a great clearance sale shopper). The fabric is unexpectedly different! It’s VERY light, and it’s a bit more forgiving/less clingy than other similar shirts, which I especially appreciate in these lighter colors and as a new mom who is still trying to get my confidence back. My only complaint is that larger sizes tend to just mean longer, not broader in the bust or shoulders. I ordered a large so it would be a little less clingy across my chest, and it fits well there, but there is so much extra fabric through the middle that once I tuck it all in, I feel like it will look a little frumpy under my white breeches. I am 5’6 with a long torso so I’m not short either! Luckily my jacket should cover it, but I’d love to see large be larger in the area where a lot of women really need it vs just more material at the bottom. Overall, this surpassed my expectations and think it’s a great buy for the price and love the color options too! I texted several friends to give them a try after I tried it on :)
Store owner replied:
Thank you for such a thoughtful review, Olivia! We're glad the lightweight fabric and colours exceeded your expectations, and we appreciate you recommending us to friends. Your detailed feedback about the balance of chest room and body length is especially helpful.
Store owner replied:
Thanks, Shawn! We're happy you like the look of the Ultra Breathable Short Sleeve shirts.
Love shopping with this brand! The quality and price of the shirts are amazing and I can’t wait until I get to show in them!
One comment is to buy a light colored sports bra - black might show through just the littlest bit.
I will definitely be buying more!
Store owner replied:
