1. Suits the swimmers wear are far more substantial than the beach volleyball suits.
2. I didn't think water drag was a major issue in beach volleyball.
3. From the article: "Men’s beach volleyball attire also illustrates that near nudity is not required to play the sport well. The men do not play wearing tiny swimwear. They wear ample shorts along with t-shirts or tank tops."
I guess you missed the male swimmers. The male swimmers are down to small strip of cloth on the bottom.
Maybe they should wear a onsie like the woman swimmers do so their chests are covered since it doesn’t difference.
