Who This Jacket Is For
This long sleeve jacket suits anyone who wants light thermal coverage on the water without committing to a full wetsuit, whether that is an early morning paddle, a boat day, or a cooler afternoon surf session. The boardshort connector means it layers naturally with the boardshorts you are already wearing, and the front zip makes it easy to put on and take off between sets.
Wear, Break-In, and Care
Rinse the jacket in fresh water after use to protect the flatlock seams and the UltraFlex material, then hang it to dry away from direct sun. Work the front zip gently rather than yanking it, and check the hand cuff stitch sleeve anchors periodically since they see repeated stretch at the wrist. Pairing it with a sleeveless full suit on colder days extends how long you can comfortably stay in the water.
