Refund Policy

Refunds and Returns

At Sweatshield Undershirt we want our customers to be completely satisfied and we have total confidence in our product.

If you are not completely satisfied with your purchase, you can return your order for a 100% refund, as long as no more than one shirt of the same type has been worn. You can return your purchase for up to 30 days from the purchase date.

The 100% guarantee does not apply to goods purchased during a sale or to goods that have been previously exchanged.


Returns Process

Requesting an RMA

To return a product, you must first request a Return Merchandise Authorization number. Please send your order number (on your email receipt) and your reason for return or exchange to service@sweatshieldundershirt.com with "Return" in the Subject Line.

Any returns without an RMA will not be refunded.

Packing and Shipping

Once you receive your RMA number, generally within two days, please securely pack your shirts. We are not responsible for items damaged in transit back to us. Please include either the return email or the order packing slip with the RMA number written on it.

After you've received your RMA and packaged your items, please send them to

Single Undershirt Purchase – Refund Policy

We'll refund 100% of your money for any single item purchase within 30 days, even if the item has been worn. 


Multiple Undershirt Purchase – Refund Policy

Please try one undershirt first as your test case. If you are not completely satisfied then return all of the undershirts to us for a 100%% refund.
