I just ruined a pair of $50 dollar shorts a few days ago by washing them with my gloves. The velcro caught on the lycra and totally frayed up an area the size of a few square inches.
I'm going to be a cheap ass and return them at to the store. I had just bought them and wore them once before washing them.
So, the moral of the story is Don't be stupid like me! Wash your gloves seperate.
I wanted to choke the life out of those gloves, until I realized they weren't alive in the first place...
