Okay, so no, you have to wear a gi on the mat. But this is the House of Combat BJJ team in Toronto, Ontario:
Comment from the be-skirted: “I was the only one who showed up in paint-able clothing. Luckily, there were a few camo suits available for everyone else.”
Camo doesn’t make you a good paintballer, though. They dropped like flies, and only three survived the campaign. One of them in a skirt.
