What is your return policy?



Click Start a Return to begin the return process.

We stand behind the quality of our products and want to make sure our customers are completely satisfied.

Your satisfaction is guaranteed for a full 60 days from the date of purchase.

If you are not entirely satisfied and would like a refund or exchange, simply click on the link above to begin our self-guided return process.

If a product arrives damaged, or we made an error that cannot be remedied with replacement items, we will pay to return the product to us and send a replacement to you.


To qualify for a full KOS refund, we require the KOS Product labels in a letter envelope with your Return Authorization # (RA#) written on the front.

Your RA# will be provided to you in the subject line of the email you receive upon submitting the return/exchange request form.

It is your obligation to pay the return postage, and we do recommend you opt for tracking and confirmation numbers for verification of delivery. We must receive the label(s) within 60 days from the date of the original purchase for the refund to be valid.

If you need assistance with your return, you may also contact us at 1-844-586-4567 Monday through Friday between the hours of 9:00 am and 5:00 pm Pacific Time, or by emailing us at hello@kos.com
