Fit tips
We recommend you go down a size in this model if you want a more contoured supportive fit, as the modal fabric is very stretchy.

One the best underwear I bought in a long time. Will buy more.
I ordered and really liked the socks so thought I’d try 1x pair of trunks as they are not cheap. Soon as I wore them I went and bought another 5 x pairs, the 20% discount didn’t work online so I emailed them and Val sent me out another pair straight away so all in all I am very happy with what is the comfiest trunks I have ever worn.
Product is really good and service faultless. What more could you want. Thanks.
Been the best I’ve worn to date it’s all I wear now
