ACCLAIM Fitness Dubbo Brief Trunks Mens Tie Cord Retro 1970's Swimming Slim Fit
I actually own a pair of Acclaim swim briefs in a purple pattern, they are well made and comfortable, I even wore them in an indoor pool at Camping Vitamin, Dieppe France.
A Tarzan loincloth consists of 2 parts, a belt and a long cloth. Put on the belt then stand over the cloth, tuck the ends of the cloth through the belt at the front and the back and gently pull from both ends.
A common mistake is to use string, under pressure the string comes undone and oops!
Another mistake is to have the front and back of the loincloth supported from the belt with nothing in between, don't bend over or swish about violently.
I had a shock seeing Louis name here, he was a friend some time before Covid, he was old and unwell then following pneumonia. He lived in Montreal, Canada close to the Olympic Stadium and Pool. He was an avid speedo collector.
