Features That Matter

Sometimes the best things in life are not spoken about. Comfort is something we all expect and we only realise that it's missing when we feel discomfort. Crossfly underwear is built to ensure all day comfort whatever you're doing. We've taken care in choosing super soft fabric mix and created some amazing features including the Dri-PX2 and ZeroFold 360.

dri-px2: Clever & discreet

This clever design makes sure that excess moisture is hidden with our 'no show' dual layers. This uses lightweight breathable fabric that is so soft, you will get that instant "ooh!" moment.

Zerofold360 Waistband: stays in place

The ZeroFold 360 waistband featured on all our underwear is made to ensure it stays in place whatever your movement. We don't want you to always be adjusting them.

Our Everyday Series goes a step further to ensure comfort to the max and you'll find a brushed finish on the inside of the waistband for next-to-skin softness.
