Summer Leagues

Be Active & Get Social This Summer!

We've got the most fun leagues in Chicago.

Summer Seasons Start in June & July

Sign Up A Full Team, Join With Friends or By Yourself

Full teams join all the time, plus we create free agent teams in each league that include coed players around the same age. Sign up and request to play with friends and you’re guaranteed to play together. Or join solo! That’s common too.

–

We pride ourselves in running the most organized & SOCIAL leagues that you’ll ever play in. And we’re the ONLY leagues where after games ALL teams walk to the same nearby bar for post-game parties and exclusive specials!

–

As an independently run and Chicago based league organization, we’re proud to offer the lowest prices while still providing the best overall league experience! Our full team fees are $100-$200 less for a season than other leagues in the city. Free agent players save $25-$35 too! And first time groups of 3+, email us for a special discount!

What are YOU gonna play?

We only run coed, recreational leagues! ALL skill levels are welcome!

NOTE: Each summer league starts right after the spring season ends, but may be delayed due to rainouts. If there is a delay in your summer league start date, we will email you with that update as soon as it happens.

  • Out of all of the rec sports leagues in the city, S3 has some of the lowest league fees, yet somehow they're some of the best organized leagues. I've done at least one S3 league every year I've lived in Chicago. It's an amazing way to meet people and make friends.

  • If you want to have a fun active summer, join the S3 volleyball league. I've been playing in this league for over 3 years and have met some of my now best friends because of it. Great way to get active and socialize after at a local bar that sponsors the league.
