Chicago didn't need another party. It needed this one.

BearUnion was built around a simple idea: create a space where bears, cubs, daddies, pups, admirers, and friends can gather, connect, and be themselves without pretense.

Every month, Cell Block Chicago becomes home to one of the city's favorite bear gatherings. Some people come to catch up with old friends. Some come hoping to make new ones. Some come because they know exactly what happens when a room full of bears gets together.

June is a little different.

For PrideFest, we're giving the Bear Social an Underwear Party upgrade.

The front bar remains free and open to everyone from 3 PM to 8 PM. Underwear is encouraged but not required. Jockstraps are welcome with a modesty cover.

We're also introducing optional stoplight bandanas:

Green = I'll tell you when to stop
Yellow = Ask first
Red = Look, don't touch

Bandanas are included with every BearUnion back room ticket and available separately for Bear Social attendees ($5).

The back room will operate much like it always does, with one adjustment for this event: underwear or less will be required for entry.

Most importantly, we're expecting one of the largest crowds BearUnion Chicago has ever seen.

PrideFest brings thousands of people into the neighborhood. If the back room is part of your plan for the day, buy your ticket in advance. Priority entry will be given to advance ticket holders before door sales if lines or capacity become an issue.

The good news?

Ticket prices remain exactly the same.
$15 in advance.
$20 at the door.

No PrideFest surcharge. No special event pricing.

Just a bigger crowd, a little less clothing, and a whole lot of reasons to arrive early.

Same community. Same BearUnion. Different dress code.
