Performance Meets Precision in the Saddle

Finding a pair of breeches that actually stays put through a sitting trot or a long day of schooling shouldn't feel like a chore. The Aubrion Optima PX Breeches by Shires are designed to feel like a second skin, giving you the support you need without the bulk of traditional riding gear. Whether you're in the dressage ring or out on the cross-country course, these breeches move with you, not against you.

We know the struggle of gear that loses its shape by the third horse of the day. That’s why the Optima PX focuses on 360º contour support and a high-waisted fit that keeps your core stable and your silhouette sleek. From the perforated ankle cuffs to the lattice silicone grip, every detail is built for the rider who demands performance and comfort in equal measure.

Absolutely. The white version of the Aubrion Optima PX Breeches is GB Competition compliant, making them a staple for dressage, show jumping, and eventing.

Q: What is the benefit of the lattice silicone grip?

The subtle lattice print provides the "stick" you need for a secure seat without the heat or restriction of a traditional leather or suede full seat.
