TEN THOUSAND X BIRDWELL

Birdwell has been at the epicenter of California surf culture since 1961 when founder Carrie Birdwell Mann turned her Santa Ana home into one of America’s first surf shops, hand-making the first pairs of “Birdwell Beach Britches” on a sewing machine in her living room. These humble origins and commitment to craftsmanship are the backbone of the all-new Ten Thousand x Birdwell Collection, blending California surf heritage with purpose-built performance and NYC grit.

At its heart are the iconic Birdwell 300 Boardshorts — same timeless look, now re-engineered with performance fabrics that are made for both surfing and training. Alongside them, a co-branded Core Tee and Tactical Hooded Shirt deliver everyday style and versatility for everything beyond the shoreline. Whether you're chasing sets or smashing reps, this collection is built to keep up.
