The underwear is quite nice , but after wearing few days I found that the material was forming pilling specially between the legs area . I don't know how durable the item would be.

Comfortable and a good fit

Comfortable with a little bit of padding. Fits well - I am a UK 10. The look pretty good too.

Awesome pants

They look and feel great,a perfect fit, I love them

My everyday favourite socks.

Just the right fit and love the cotton feel.

Great socks

Great socks at a great price👍

Socks for running

IKON 3" Trunk
Brandon Hanrahan

The pouch doesn’t really do much good, the lads seem to fall out.


Retry comfy but expensive


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.


great socks ,really comfortable ,great fast service , highly recommend .

PRO 7" Boxer

Good product, not good service

The actual product is good and I think I’d really like them. There are two issues: 1) I apparently need a smaller size than what I ordered. So I followed the return/exchange instructions but never heard back from the company. So I’m stuck with underwear that is too big. 2) the pouch in front doesn’t contain everything where it’s supposed to stay. Was hopeful, now disappointed.


Very comfortable and sit well in my trainers. Pleased with them.

A bit disappointing

I bought a pair of these as a trial, but they don’t work for me. The ‘separation’ isn’t as good as some other underwear and they rode up quite a lot. The material is really nice.

Crossfly Men's Trunks - IKON 3" - NAVY

Great for Golf

I gave this pair to a mate for his Birthday who plays a lot of Golf. He says the easy access is a game changer on the golf course and that they are so amazingly comfortable. He's going to buy a load more.

IKON X 6" Boxer
J Trevino

Sizing chart way off didn’t enjoy product at all to loose to enjoy. They look and material feels amassing but no

Hi there. Thank you for taking the time to post a review and for your feedback. We are committed to offer a great product and also clear advice on our sizing. We apologise if that was not clear when you placed the order.

The IKON and IKON X underwear does come up stretchier due to the Modal fabric and we therefore ask that our customer opt for a small down than usual. Of course, each person has their own preference regarding fit.
Kind regards, Val

Only the best

I had purchased some on trial and they were so good I took advantage and purchased some more. To date the best I have had.

Very comfortable

Very pleased with my purchase. The boxers are so comfortable and keep your bits in place when doing sport. Socks are good too. Will be trying the Everyday Boxers next.

Boxers review

Comfortable and they don’t go baggy which is the best thing, look and feel smart too

Comfort and ease

My Crossfly trunks look nice, are very comfortable to wear and the fly opening across the top is very handy - no fumbling to find the fly. Crossfly is especially handy if you have a sensitive bladder and can ill afford any delay.
