From looking at the Croks photos on their WS, I have the sense that it is very much a 'social' sporting group & don't take themselves too seriously. E.g. camping trips, soft croc award etc. Seems like having a laugh & fun is the focus so am guessing anything, within reason is ok. Back to the gold shorts.....no I don't think they're silk boxers.....too fitted & fabric seems much heavier than silk ....IMO
