SF Catalyst is a community-run educational and social space, operated by the SF Bay Area Leather Alliance.  SF Catalyst has a commitment to diversity and inclusion, to providing space for community organizations to further their programs and missions, and to working with other existing San Francisco Leather community spaces to ensure the long term vitality of the SF Bay Area Leather community.

Entry is $30 which includes a FREE CumUnion membership card and a private locker and gives you access to 2 levels of play areas packed with loads of hot men, fuck beds, tons of kinky play equipment, free condoms, and much more. ID Required for entry and locker key deposit.

Beginning on Monday, June 28th, 442 Events will return to hosting play parties at SF Catalyst every Monday and Tuesday at 8:00pm as well.

**During certain months the 4th Friday CumUnion party will move to the last Sunday of the month to align itself with certain special events weekends.  (i.e. July for Dore Alley and September for Folsom)
