Once a year, MAFIA takes over Steamworks during the most prestigious weekend in leather. Our biggest Invasion of the year brings fisters from around the world together on the third floor play space to show off, connect, and remind everyone exactly what Chicago does best.

The biggest perk? MAFIA priority entry. IML weekend means the line at Steamworks wraps around the block. MAFIA members and Invasion guests skip it entirely. While everyone else waits outside, you'll already be wrist deep in the action.

As usual, we are taking the whole 3rd floor gym at Steamworks Chicago. Party starts at 9pm.
