Size Guide

Choosing your size

We want you to shop with confidence when buying new rubber online. Our updated size chart provides consistent sizing across our entire range, with additional reference points and improved diagrams to make choosing the right size easier. For the most accurate results, use a soft measuring tape, measure yourself barefoot in your underwear, and simply review the tabs in the size chart below.

Sleeve and leg lengths are designed to fit average sizes; if you feel you may be particularly tall, short, or need further assistance, please contact our customer services team for guidance. We're ready to assist with sizing advice, alterations for taller or shorter customers, and details about our Made-to-Measure Service. If you’re unsure about your size or have specific fit requirements, please email us at [email protected] and we’ll be happy to help.
