Sharkskin Unisex Rapid Dry Short Sleeve Rashguard Top

Quick answer: The Sharkskin Rapid Dry Short Sleeve Top is a lightweight, fast-drying technical T-shirt for on and around the water. It has a standard neck, a loose T-shirt cut, four-way stretch, a durable water-repellent treatment and UPF50+ sun protection. It's unisex and comes in sizes from 2XS all the way to 5XL.

Why bigger divers look at it

Most rash guards are cut skin-tight, which isn't everyone's idea of comfortable. Sharkskin went the other way. Rapid Dry is cut like a relaxed T-shirt and doesn't cling or restrict your movement, and Sharkskin says it looks good wet or dry. With sizes up to 5XL, it's one of the more inclusive tops in the category.

What the fabric does

Sharkskin says Rapid Dry is warmer and more insulating than cotton and nylon, lycra or spandex fabrics, wet or dry. A 3-D rib-knit construction adds insulation, and the water-repellent treatment is infused and heat-set so it lasts longer than traditional coatings. The fabric resists UV, saltwater and chlorine, breathes to help regulate body temperature, has non-chafing seams and resists odor. Wear it alone, or layer it over other Sharkskin tops for extra warmth.
