Don't much like his speedos and not all the shorts but some pleasurable research undertaken from which I conclude:
Cheap at £2.95 and in the white pics I think I see some broad vertical stripes of a modesty speedo beneath.
These shorts do not appear to be fully split with side seam overlaps but are sufficiently so to go beyond describing just as with side notch . I am in some confusion however as I think I see a second seamline but only in that with blue braiding.
(Torchwatch must assist me there)
Whatever, there is plenty to see on his Ebay page and also in Google Images.
(btw do we not have or used to have a board member from Brighton?)
