IKON & IKON X styles: (Choose one size smaller)

This style is made from Modal fabric which is quite stretchy. As such, we recommend that you order one size smaller than your usual size for a better fit.

Our customers find this style fits true to size.

 

How to measure

  • WAIST: Measure around the narrowest part (typically where your body bends side to side), keeping the tape horizontal.

They are good

Finally found some underwear that keeps my private bits in place

Great for the Gym!

I find the Pro 7" gives the right amount of compression for a workout, with the added technical benefits of the Crossfly support and fast fly access. The material also seems to dry out quickly.
