Clayside is a direct-to-consumer brand built for the modern tennis player. We design refined apparel, performance footwear, and considered accessories for those who live the sport on and off the court — from baseline rallies to everyday wear.

For players who care about how they move and how they look while doing it. Whether you're training, playing club matches, or carrying tennis style into your day, Clayside is built for the new generation of players who want both performance and design.

Clayside is an international direct-to-consumer brand. We ship worldwide from a curated network of fulfillment partners, serving customers across the United States, United Kingdom, Japan, and beyond.
