International orders are shipped either DHL or UPS with an estimated arrival time of 7 to 21 business days, depending on the destination. Please allow 1 to 2 days for processing orders. (Please allow for extra time during sales and holidays.)

First Pair Guarantee

If you find that SHEATH is not right for you, or if you think one of our other styles would suit you better, we will either refund or replace your first pair without question within the first 30 days of receiving them. Refunds will not include shipping charges. We recommend only ordering a single pair for your first time trying our products to see if SHEATH is right for you.

We have a strict return policy in place for the health and safety of everyone.Ā In order for an item to qualify for return or exchange, it must be: unopened, unworn and in the original condition it was received.

ALL ORDERS PURCHASED WITH A GIFT CARD ARE FINAL

ALL ORDERS PURCHASED USING THE BUILD-A-PACK DISCOUNT ARE FINAL

Free Shipping

Shipping is free for all US orders over $120 USD. All other worldwide shipping is free for orders over $250 USD.

Returns/Refunds On Orders That Qualify For Free Shipping

If your order qualified for free shipping and you have tried a single pair from your order and have decided to return the remaining unopened items for a refund, we will refund the amount paid in full minus the cost of return shipping once the unopened items have been received and inspected. Return shipping rates will be determined by location.

Returns/Refunds On International Orders

At this time, we do not accept international returns.

Due to the high and unpredictable cost of international return shipping, processing returns from outside the United States has become impractical for both our customers and our small business. In some cases, return shipping fees can exceed the value of the items being returned.

However, if you have purchased items internationally that you are not satisfied with, we can provide store credit or, in some cases, a refund— without requiring you to ship the items back.

This policy applies to all international orders placed on or after Monday, December 1st, 2025.

We strongly encourage international customers to review our size guides carefully and reach out to our support team with any questions prior to ordering, we’re always happy to help.

Defective or Damaged Items

SHEATH stands behind the quality of our products and their performance 100%. We offer a 1-Year Manufacturer Warranty to cover any defect in fabric, construction, finish or workmanship (this does not include stains from regular use or incidental damage i.e. cigarette burns). In the event of a confirmed defect, we will gladly ship out the replacement piece at our cost. Please send a photo of the affected area and description to contact@sheathunderwear.com. Only the defective item(s) of the order will be replaced.
