it's really hot where I am and I would prefer not to wear a shirt when racing but most races want you to wear shirts. I am trying to find something that is technically a shirt but covers as little skin as possible, whilst not looking like one of those borat swim costumes.
so the back should just be a thin piece of fabric between the shoulder blades, down the spine. and the front should have a very deep U neck.
is there a name for this, when I search I mostly get gym clothing in the results.
also is there such a thing as 'sports bra'/'crop top' for men that isn't designed for gay people? if not somebody should invent it. footballers wear them to monitor heartrate but I've never seen them sold as an actual piece of standalone clothing.
