Built for the Long Sessions on the North Shore
Some mornings on Kauai the swell is small and the water is glassy, and other days the waves stack up and you spend an hour paddling out before the first set. Either way, a long sleeve rash guard earns its place in the bag. The Koloa Vintage Surfboards Long Sleeve Rash Guard was made for those hours on the water, when you want your arms covered and your shoulders protected without giving up freedom in the paddle.
Pull it on after a rinse at the outdoor shower, grab your board, and head down the trail. Whether you are chasing a mellow longboard session or trying to stay out for one more wave as the sun drops behind the cliffs, this rash guard keeps you comfortable and covered. It fits the island lifestyle the way we live it: practical, relaxed, and ready for whatever the ocean brings.

Fit and Sizing
The rash guard has a comfortable fit with raglan sleeves that allow a full range of motion across the shoulders and chest. Underarm gussets add flexibility where you need it most. Because stretch fabrics can fit differently from person to person, we recommend checking our size chart before you choose your size. If you fall between sizes or need a larger cut, our big and tall surf apparel page can help you find the right match.
How to Wear It
Wear it on its own for a clean, sun-protected look after a morning surf, or layer it under a board short for a full coverage setup on bright, exposed breaks. It also works well as a sun shirt on the beach, on a hike to a lookout, or during a long day on a paddle board. Pair it with your favorite Koloa shorts and sandals and you are set for the rest of the day.
Care
Rinse your rash guard with fresh water after every session, especially after saltwater. Turn it inside out before washing and let it air dry out of direct sun. For washing instructions specific to this piece, please follow the care label inside the garment.
