Being Cool Just Got Easier.

We at ThermApparel are all about breaking barriers, whether it's temperature-related or not.

To help with financial barriers, ThermApparel currently partners with MS Focus and the National MS Society to help people living with MS purchase a cooling vest.

To help all our communities Affirm is now available to add flexibility to your payment options.

  • Your rate will be 0–30% APR based on credit and is subject to an eligibility check. Payment options through Affirm are provided by these lending partners: Options depend on your purchase amount, and a down payment may be required.
