The Thermalution models have unisex sizing. They are highly elastic and designed to stretch to fit many body types. If you find that you are in between sizes, we recommend that you go with the larger size. If your Thermalution does not fit extremely tight, it is not a problem. When your form-fitted wetsuit is placed overtop of the Thermalution, the wetsuit will help to press the heating areas firmly to your body.
We recommend all customers to try the Thermalution Heated Wetsuit products on at home BEFORE removing the tags. If the sizing is slightly off for any reason, you can return the suit at no charge. We will ship out the correct size to you the same day your suit arrives back here at the shop.
