Three years in the making, this is the second generation of Kelly’s APEX Trunk. We took the most high-performance trunk ever made — and made it even better.

We delivered on Kelly’s precise design requests: better no-slip braided drawcords, an enhanced waistband that cinches without bunching, and reinforced ultrasonic-welded seams where it matters most.

We teamed up with our friends at Bureo for their matchless NetPlus® material made from recycled fishing nets. This yielded a truly responsibly made trunk with a little more substance than the first APEX—without compromising any performance qualities.
Part of Kelly Slater’s Signature Collection, this style features the iconic OK KS Portal logo in Ocean Blue at the back pocket and Ocean Blue OK Dot and Wordmark branding detail.

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

Performance-centered design details throughout:
  • Pitched forward side seams with vents for easier fit on the board.
  • Unique arc and tangent shaped back pocket featuring a key loop and eleven laser cut drainage holes, one for each of Kelly's world titles.
  • Engineered side seam taping.
  • Soft touch interior waistband.
  • Gusseted fly.
  • Soft touch triangles at inner thigh touch points.
  • Unique rubberized drawstring.
