At very FIRST wearing, as I'm 15 minutes into an elliptical workout - and yes, sweating a LOT - I felt a coolness around the crotch area. Like air to a sweaty area, cool, and sure enough the ENTIRE AREA WAS RIPPED OPEN!!
I also have an Everlast sauna suit that I've had and used for OVER THREE YEARS with NO damage. It's thick and durable, but it's ugly and ROBOT SILVER, which is why I got this Altus one so that I could blend in a little better at the gym and not feel embarrassed. Needless to say, having the crotch area ripped apart was 10x more embarrassing.
I think I'll just look around to see if Everlast has another color.
