Allday Boxers

Adam R.

They are crazy soft and comfortable. They are pretty long. I would like to try the shorter boxers next time.

Great customer service

Les C.

I made an error when I ordered, but the support agent didn't make me send it back, instead they sent me a free pair. Great way to treat customers!

Great Purchase

Andrew K.

Bought an Allday-Flex Bundle 4 pack. Tried them on the day they arrived and immediately went online to purchase another 4-pack. The Alldays are super soft. The Flex are more like moisture-wicking sport briefs but still very soft. Both keep you dry all day and are great for either work or working out. The colors are slick too. These are easily the best and most comfortable trunks I've ever owned.
