Experience unrivalled comfort and support from our patent-pending innovative internal pocket system, the Coccoon. With this design, skin on skin friction and chafing are removed.
All our underwear is made from premium fabrics. In our Everyday Series, the IKON and IKON X styles are made from super-soft and sustainable modal fabric whereas the Pro 7" features an ultra-breathable mesh fabric made from nylon.
These trunks are by far the most comfortable I’ve ever worn. The crossfly or ‘hole’ is extremely easy to use and keeps any pressure off your hose when going to the toilet. Must buy.
I’m loving the Icon X 6” boxers, what a great design and very comfortable
Socks are amazing. Keep my feet sweat-free and so comfortable to wear.
Good length, comfortable material and finally a pair that stays in place during my runs. Well recommended 👍
Bought one pair of Crossfly Ikon Trunks a few weeks ago for husband to try. He said they were the best ever and the most comfortable. Washed them a few times - still perfect- so treated him to 5 more pair. Excellent Customer Services as well.
These boxers are awesome! Lots of thought has clearly gone into the design. They are super comfortable for general day to day wear but also for high intensity training and spinning.
I've been searching for a long time for quality underwear at affordable prices, and Crossfly fits the bill.They are really comfortable and stylish.
Extremely comfortable, keeping everything in place. The material is superb.
They are a joy to wear
These socks are the perfect combination of thick and thin that I love in Athletic Socks. They absorb sweat well, and the fit is perfect. And the value for the cost is excellent.
The Crossfly Ikon is the best underwear I have ever used for Golf, period! I get zero chafing because of the internal pocket design, and the fast easy access fly is just a brilliant idea for on the course. All Golfers need to try these out!
I received an order very quickly, came in great packaging. Socks are super comfortable they are my new go to socks.
Once I found my size they are nice, plush and snug.
Fly works well and I will probably add a couple more pairs to my collection soon.
Well done to the genius inventor..!
Far and away the most comfortable underwear and socks I have ever worn!
I’m a regular runner and the Vent sock is now my go-to favorite pair. They are really breathable and the sculptured fit means there is no extra movement. All runners need to try these.
At first, I was concerned that the shorts might rise up my thighs when running. My normal Runderwear shorts do this, and they even have a rubber strip along the inside edge of the leg to hold them in place. I was quite surprised to find that the Crossfly boxers didn't do this - they didn't rise at all!
