Sharkskin Thermal Flex Swim Jammer (Women's)

Ladies who swim laps in open water or spend an hour floating over a reef know that standard swim bottoms do nothing to hold heat. The women's Sharkskin Thermal Flex Swim Jammer changes that with a thigh length cut in a warming fabric that still feels like regular swimwear. It is new for 2026 and suits swimmers and snorkelers alike.

Warmth Without Neoprene

Each pair is made from Sharkskin's Hydrophobic Nanotech Compression fabric with Far Infrared (FIR) technology woven in. The result is extra warmth with none of the thickness or lift that neoprene shorts add. Because the fabric repels water and barely absorbs any, it stays light in the water and dries off quickly, and the lower drag helps your swim pace.

The fabric carries UPF50+ sun protection, so your thighs stay covered during long surface swims or while you wait on the boat.

Women's Fit and Sizing

Women's sizing goes from US0 to US16, with a cut shaped for a women's hips and waist. The compression fit should feel firm but not tight, and it holds its shape through kicking and paddling. For matching warmth up top, add the women's Thermal Flex Long Sleeve.
