Flow+Vibe Unfiltered Halloween Edition

October 31, 2025 @ 5:00 PM - 6:00 PM

$24

Unedited, untamed, and unmasked – unless you want to dress up and wear a costume…the option is yours.
For the thrill-seekers…the Halloween spirit will be just as HIGH as the volume of the music. It’s intuitive, edgy, and set to un-edited, moody beats.
🕷️ Friday, October 31 at 5:00pm at our O’Fallon Nest
Expect TRICKS on the mat followed by post-practice TREATS.
Boo! 👻 Anything goes…dare to lean into the vibe.
Sign up online or by downloading the Moonbird App on your phone and choosing the O’Fallon location.
