A Faster, Easier Way

Just reach through your trouser fly and pull down on the Thumb Tab!

No more unbuttoning your trousers or pulling down the waistband of your underwear. Our patent pending technology creates a short cut to simplify the process of taking a leak.

Because X is why

Y-Fronts have been around since 1934 and in nearly a century Men's underwear has not really moved on. We decided it was time to reboot the system; and in the process we found that X is better, faster, easier... and X is WHY.

Just reach through your trouser fly and pull down on the X-Fly Thumb Tab!

Take a pair of these for a test drive and we promise you'll never look back. The X-Fly just makes too much sense, (and sometimes speed really matters)!

Thumb Tab

Locate the X-Fly opening easily with the Tumb Tab, which features a tactile Crossfly logo.

Whether you're in a rush or in the dark, the Thumb Tab guarantees immediate access. A small but very effective feature.
