I'm with you here especially in country towns where gyms are tin sheds no air con. With temps getting to 40 Celsius (100 degrees Fahrenheit) crops and bike shots are defiantly the best option. All of our Australian leotard manufactures make half tops so we have the same if not more choices in half tops compared to leotards.In summer way down under in our part of Australia it gets very, very hot.
Croppies are absolutely the favourite thing to wear-here its a safety issue where gymnasts simply overheat if not allowed to wear a crop top.
Generally they start the morning session in a regular leo, then change as the day warms up. Afternoon sessions they usually start in a crop top.
No air cons here! just a big tin shed with a few small doors that can be opened and 3 small Windows!!Don't you guys have air conditioning in Australia? I'm in Texas, where it gets over 100 degrees routinely from late June until September. Our gyms have ac, so heat would not play a factor in workout clothing.
Our gym is leotards and bootie shorts for the girls who like shorts. Between gyms for both kids and weekend training events, I've watched practice at six Texas gyms. I have never seen an exposed midriff. (And our boys all practice with shirts on, too.)
