Beat the Summer Heat in the Saddle

When the sun is beating down on the arena and you’ve still got three horses to work, the Shires Aubrion React Sleeveless Base Layer is your secret weapon for staying cool. Designed specifically for high-intensity riding in peak summer temperatures, this technical top moves with you, ensuring you never feel restricted whether you're posting at a trot or clearing a jump.

Crafted with Shires' signature attention to detail, this base layer isn't just about looking sharp—it’s about performance. The sleeveless cut offers maximum ventilation, while the advanced fabric technology works overtime to pull moisture away from your skin, leaving you dry and focused on your ride rather than the humidity.

Frequently Asked Questions

Q: How does the sizing work for Shires apparel?

Shires uses UK dress sizing, so a UK 10 typically fits like a US 6. We recommend checking your chest measurement in inches against the size chart for the most accurate fit; if you are between sizes, it is best to size up for the most comfortable fit in the Shires Aubrion React Sleeveless Base Layer.

Q: Can I wear this for cross-country?

Absolutely. This sleeveless base layer is a favorite for eventers because it wicks sweat away effectively under a body protector, preventing the overheating often caused by bulky safety gear.

Q: Is this base layer supposed to be tight?

Yes, this top is designed with a body-skimming, "second-skin" athletic fit to maximize the moisture-wicking properties of the fabric. If you prefer a looser style, we recommend sizing up significantly.
