COCCOON™

Our patent-pending innovative internal pocket system provides greater comfort and support, eliminating skin on skin friction and chafing, keeping you cool when it matters.

Simply put, the Coccoon separates your private parts from your thighs.

DRI-PX2

Our ‘No Show’ Dual layer protects against excess drips and moisture. Its technical qualities and light breathable fabric ensure you’re comfortable all day long.

Extremely comfortable, keeping everything in place. The material is superb. They are a joy to wear.

X-FLY & Thumb Tab

Our patent pending technology enables easier, faster access through your trouser fly, removing the need to reach in and pull your waistband down or to undo your trousers.

The Thumb Tab central locating point enables you to find the Fly with ease.

So comfortable and perfect for any outdoor activity. The quick and easy access is ideal, especially when you’re supposed to be taking your next (golf) shot!
