Product Description

The UnDBoxer by DeFeet is made to keep you more comfortable while you ride, run, and just hang out. The UnDBoxer is more suited to the "hanging out" part of that equation. For those that want a tighter fitting, supportive underwear, there is the UnDBrief. We developed this eco-friendly mesh fabric specifically for the UnDBoxer. The result is underwear so light and stretchy you forget you're wearing them - all while keeping you drier and feeling best right where it counts. Leave the torturous underwear of the past behind. If you prefer a looser fitting underwear bottom and still want quality and performance, free yourself in the UnDBoxer. Made with Repreve», a recycled fiber from Unifi.

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
