4/3mm Jersey Wetsuit

A cold-water wetsuit designed for women's bodies. Handcrafted in Japan, one at a time.

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.

Fit notes

f 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.
