Gift Pack

Buy 1 Underwear,

Like having your man parts cupped by angels
Gavin Berry

IKON X 6 - Navy

...When I put on my Crossfly Boxers, I feel 18 again. I don't like spending money on myself, especially on something that's invisible to everyone else, but in this case it's justified. The effect is instant and lifts my spirit too. And if anyone asks why I'm smiling I'll tell them that it's because I'm not looking anymore for something I didn't know I needed until I found it. Trust me, you won't look back.

3 pack: IKON X 6 - White

Not usually one to get excited about underwear but these are amazing. Have been looking for something to replace my Calvin Klein cotton stretch trunks and these are so much better. Great design, perfect fit and material.

Great fit and very comfortable. No sweat, no riding up. Will buy again.
