The popularity of swim briefs---then and now

[Torchwatch]

The expensive jammers are made from sharkskin fabrics that move through water with less drag than naked skin, the full body sharkskin suits were banned as giving swimmers an unfair advantage.
Lycra jammers have more drag then naked swim and therefore make you swim slower.
You even need instructions on how to put expensive jammers on :

Sport i Euro Question. What is the difference between Sport i Euro and the i Swim briefs? Has a any one tried either of both with the liner removed?

The liner causes everything to be flattened out and squashes the ball sack. Does liner removal ease that without being modest enough for the gym pool?

There is a Sporti Euro ( 1 1/2 to 2 inch side) and a standard Sporti brief (2 1/2 to 3 inch side. The iSwim brief is similar to the Sporti non euro brief, but generally cheaper. The iSwim I think is made by the company that used to make a brand called ClubSwim. I think they are basically the same thing.

The Sporti briefs have a rather confined pouch, but that is part of the idea. The Euro version is more nearly an Asian style brief than a Euro style brief. Small pouch, cut low in back. That look appears to be becoming increasingly popular, and Swimoutlet claims that both Sporti styles are best sellers. There are lots of comments on all of them that are, well, interesting to read, and in places, quite candid about specific size issues.
