Outerknown - APEX Evolution Trunk by Kelly Slater - Storm

Overview

Three years in the making, the second generation of Kelly Slater’s APEX Trunk refines the most high-performance boardshort ever made—pushing boundaries even further.

Built to meet Kelly’s exacting standards, this version features improved no-slip braided drawcords, a re-engineered waistband that cinches smoothly without bunching, and reinforced ultrasonic-welded seams placed for maximum durability and comfort.

Crafted in collaboration with Bureo, the trunks utilize NetPlus® material made from recycled fishing nets, resulting in a more sustainable build with added structure—without sacrificing the lightweight performance that made the original APEX a standout.

Crafted from 90% NetPlus® Recycled Nylon, 10% Spandex.
