Kai Lenny & his Sup Collection by Quatro. A new era begins.

Two movements took shape on Maui’s North Shore in the early ’90s. Kai Lenny — destined to become the most versatile waterman on the planet. Forward Maui — the creative force behind Quatro and KT Surfing.

A Shared Vision.

From towing into monster waves, riding remote reef breaks, competing internationally, traveling and exploring all the waves this world has to offer then back to spending hours tweaking designs and shaping in the factory – Kai and Keith have forged a shared pursuit: to transcend boundaries in Surfing, Tow-in, Windsurfing, Sup, Kiting and Foiling. The result is relentless innovation – driving the future of board design.

Kai started surfing at 4, windsurfing at 6, Sup at 7, and foiling / tow-in by 9. He’s spent a lifetime redefining what’s possible across every discipline.

Kai Lenny: “Since 2019, Keith has shaped every board on the face of the planet under my feet. All these sports feed into each other. The more time I spend on the water, no matter the medium, the better I get — and the more fun I have.”

Since 1994, Keith Teboul has been pioneering construction and shaping from his home in Haiku, Maui, the ground zero for global wave and wind innovation. The legendary shaper of Quatro and KT, translates Kai’s unfiltered feedback into ever-evolving custom boards, spanning everything from Jaws, Mavericks, and Nazare to Ho’okipa, Indo, and the North Shore of Oahu. Now, that synergy is opening its doors.

The Kai Lenny Vault. Sup Collection.

Since his early SUP days, Kai has been pushing the limits of Sup wave riding. Constantly channeling his innovative vision and style on the water into the board quiver that he rides. Kai has become one of the most decorated athletes in Sup history, having won multiple major championships. He has won at least 8x Sup world titles which include victories in both racing and wave disciplines, not to mention the legendary Molokai 2 Oahu long distance Sup World Championship. Each model channels Kai’s one-of-a-kind riding style — sharpened from grom to big-wave icon — with refined outlines, advanced materials, and a multi-discipline mindset. His signature approach translates into this signature collection. This three model lineup, is ready to blow your mind. Covering all your needs from performance wave riding through to long board cruising.
