Peter Cordwell - 07/02/22

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

24H COMFORT & CLEVER ACCESS

The Ikon X 6" Boxer is the ultimate premium men's underwear, combining two patent-pending technologies. The X-Fly provides fast and easy access with its clever design whilst the Coccoon internal pocket support system minimises chafing, providing optimal comfort and support. Teamed with our super-soft Modal fabric, these will become your go-to favourites.

 

• Fabric: 95% modal / 5% elastane

Tony England - 21/03/22

The access vent is so perfect, no more fumbling and dribbles!

We have spent 3.5 years working on the best & most technical pair of underwear man has ever seen; and reviews show that it works. But, they’re not just technical, they are also the most comfortable pair you will ever wear.

  • COCCOON™

    Eliminates skin on skin friction and chafing providing greater comfort and support.

  • X-FLY

    Easier, faster access when nature calls.

  • ZEROFOLD 360

    Stays in place however active you are. 4-way stretch construction works with your every movement.

  • DRI-PX2

    ‘No Show’ Dual layer protects against excess drips and moisture.

Nick Bayly - 24/03/22

After experiencing sizing issues with my first pair - they come up big - I went down a size and am delighted with my purchase.
This boxer is made from Modal fabric which is naturally quite stretchy. As such, we recommend that you order one size smaller than your usual size for a better fit.

This 6-inch inseam style is a mid-rise which means they’ll sit on your hips nicely for a classic look. Not too high, not too low.

AJ Harper - 28/02/22

These boxers are super comfortable for general day to day wear but also for high intensity training and spinning.
The guy who goes between the gym and the boardroom. This versatile pair is designed for a wide range of sports from running to hiking as well as more relaxed activities.

Underpants that makes you feel smooth

The most comfortable underwear that I have ever been lucky enough to wear no matter what your age I would recommend you try a pair and will guarantee you will buy some more

Good investment

Used them for both runs and long walks with the pram. No chafing from these boxers compared to other ones in my drawer. Stretchy fabric so S suited me perfect, usually a M. Nice packaging was just a bonus 👍

Wore the IKON X 6" to hike up Snowdon and they felt comfortable from start to finish. They didn't rise up my legs either which was a bonus and the X-Fly opening really does work!

Very comfortable. Great to buy from a British company but then when you check the box they’re made in China! Duped is the overwhelming feeling. Disappointed
