When ordering outside of United States of America, the recipient is responsible for assuring the product can be legally imported to the destination country.

The recipient is the importer of record and must comply with all laws and regulations of the destination country. The recipient of an international shipment may be subject to import taxes, customs duties and fees, which are imposed once a shipment reaches the recipient's country. Additional charges for customs clearance must be fulfilled by the recipient. 221B Tactical has no control over these charges, nor can predict what they may be.

Customs, duties, and taxes are non-refundable: so a shipment that is refused because of unexpected import fees, the cost of the original shipping and any return shipping charges will not be refunded. Customs policies vary widely from country to country; you should contact your local customs office for more information. When customs clearance procedures are required, it can cause delays beyond our original delivery estimates.

To avoid a delay in receiving your order from customs, we strongly suggest:

  • Providing a phone number where you can be reached by customs when your product arrives. This phone number will be listed on the commercial invoice so customs can reach you to clear your order.
  • Please do not refuse a shipment or ignore requests from carriers regarding duty and/or tax liability charges. Be aware that most carriers will hold a shipment for 5 days after arrival in your country before they return it to the sender.

We do not refund original shipping charges for goods that are refused for delivery at customs.

                Maxdry underwear review

                I was amazed at how comfortable these underwear are. I will be purchasing another set of 3 pairs. I was also surprised that the size 32 fit so well. This was a very good purchase. I'm to old to send a picture.

                Maybe too old, but a 32' waist is pretty good! LOL! Thanks for your review.


                These aren’t the softest, but they are very breathable and they resist odors very well.

                Odor. Was. A. Problem. Not any more!

                My husband works long shifts in full tactical gear, and in the summer heat it has been almost unbearable to have him come in the house prior to showering. We had to put all his underclothes directly into the wash with a bleach free sanitizer to soak prior to washing, then use scent beads and a deodorizer detergent to help reduce the odor. We made the change to 221b underwear when we changed his shirts, and we are both very happy with the change. No more stripping in the laundry room to soak his clothes- they can be washed with the regular laundry. Couldn’t be happier with these underwear!

                Thanks for sharing Melissa! So happy to hear this product is helping. - Brad @221B

                Great customer service!

                Accidentally ordered the wrong size briefs and found the size large shirts run small, at least for me. Sent back the order and with no fuss from 221B and no extra effort from me, they promptly sent a new order. Love the briefs and shirts!
