Contact us about sizesThe 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.
