ROLL CLUB OPEN MATS. Good rounds. Good people. No politics.

Each event lists the confirmed date, check-in time, venue, capacity, cost, parking info, and mat rules. The next open mat has not been announced yet — join the email list or follow @rollclubbjj for the first update.

MAT ETIQUETTE: Arrive clean, with trimmed nails and clean gear. Wear footwear off the mat; no footwear on the mat. Respect taps immediately and match your partner's pace. Stay home if you have symptoms of illness or a skin infection. Follow venue rules and the host's direction.
