There was a time when most multisporters, yes even duathletes, owned 5+ budgie smugglers. We didn't know why but we just did race in tiny baywatch numbers and crop top vests. Fabrics didn't last yet somehow our overtrained asses did.
Now we're swim training in mid thigh swim shorts - go figure?! Some brands make hydro gliding shorts, others are designed to manage pool chemical wear and tear - each with colours and designs to suit the quiet creepers to the loud check-at-me's among our squad lanes.
Which do you swear by and would you ever race in one?
