Great fit very well made

Great pants

Really quality product and superb customer service

So comfortable

I bought some of these based on a recommendation last year. Not really being a person who has ever focussed on ‘pants’ I was a bit sceptical, but the comfort of these really has made be re-think my traditional underwear choices (which were really, put a pair on the counter whilst actually buying something else).

I would highly recommend this underwear, both the pants and the socks are comfortable, good quality and feel great

IKON Men's 6" Boxers - Green Marle

Best Socks Ever

These socks are my second lot of Crossfly socks. They are the most stylish, comfortable, hard wearing and washable socks I have ever had. Wouldn't buy any other socks now.

Super comfy pants!

I’m very pleased with my new boxers. They are extremely comfortable and fit perfectly. I really appreciate the extra length on the legs. I highly recommend them and I’ll be back to order more.
