4/3mm Jersey Wetsuit

Basalt's Jersey 4/3 is constructed of premium Japanese limestone rubber with a durable jersey shell and recycled fabric lining.

The suit is easier to slip on and off thanks to our curved front zip entry, low-profile ankle zippers, and an internal pull to help slide it off your shoulders and arms.

If you sit between sizes on our size chart, we recommend choosing the larger size. A suit that’s too tight is harder to get in and out of and will wear out more quickly. A slightly looser suit will mold to your body with wear and may shrink a bit with age. See our Fit & Sizing page for help choosing a size.
