Inspired by the topographic map of the La Jolla coastline, this kit pairs our flagship rash guard with the shortest shorts we’ve ever released: a clean 4" inseam built for movement and speed.

The Topo Kit is built with the same proven materials trusted across our core lineup. The rash guard uses durable, competition-grade fabric designed to handle tough daily training without losing its shape or comfort.
Flatlock seams reduce chafing, breathable under-arm mesh helps manage heat, and a slightly longer torso keeps everything in place when rounds get chaotic.
Fully sublimated graphics ensure the artwork looks as sharp on day one as it does months down the line.
The Topo Shorts feature a 4" inseam, making them the shortest shorts we've ever released.
Built on the same foundation as our AirFlex shorts (which have a 6" inseam), they incorporate lightweight, fast-drying fabric, a low-profile waistband, and four-way stretch that moves freely in every position.
No velcro, no bulk — just unrestricted movement and a confident fit that stays put through hard training.
This kit's design features the topographic map of La Jolla shores.
Once it hit the warehouse, our team didn’t wait. Athletes started grabbing it immediately — training in it, competing in it, and asking when they could get more.
Since then, the Topo Kit has shown up consistently in competition and hard training rounds alike.
Also sold individually as just the rash guard or shorts.
