from surf to sand

Crafted with the same shell and liner as our best-selling Set Short, these are water-ready, sweat-tested, and engineered for versatility — whether you’re catching waves or crushing workouts.

FITS JUST RIGHT

A 6.5” inseam shell and 4.5” liner hit the sweet spot between coverage and freedom, while the elastic-back waistband adapts to your every move without sacrificing a clean, classic look.

EVERY SESSION CARRY™

Premium power mesh pockets keep your essentials secure and weightless. From your phone and card to your keys, every item has its place — including a flap back pocket with bungee loop for peace of mind on the move.

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 SoCal 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.
