Product details

The shirt you'll live in. The Ultra Breathable Mock Neck Sleeveless Shirt is built for riders who refuse to choose between staying cool and looking polished. UPF 50+ protection covers you from the mock neck down, perforated panels on the chest and back; exactly where you build heat, and the buttery-soft four-way stretch moves with you from warm-up to victory gallop. Sleeveless means nothing between you and the breeze on the hottest show or schooling days.

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.

Why riders choose this shirt

  • UPF 50+ sun protection that blocks the vast majority of UV from the mock neck down
  • Ultra-breathable perforated fabric that vents heat on the chest and back
  • Buttery-soft, four-way stretch (85% nylon / 15% spandex) that never restricts your ride
  • Sweat-wicking performance that keeps you dry and looking fresh ringside
  • Flattering, polished fit that takes you from schooling to show without a wardrobe change
