I like wearing this cap - it’s lightweight and comfortable. However, I wear it to run and my sweat has made the metal buckle and loop go very rusty. This has happened really quickly - within less than a month of use. It’s advertised as a running cap, so seems strange that it reacts so poorly to sweat! Probably wouldn’t recommend for that reason, although otherwise I like it.
