Partners
Partners who bring the warmth.
Cold water is our half of the deal. Partners bring the other half — coffee, treats, and gear that make a frosty morning feel like a million bucks. This page grows as the colony does.

Third Rose Coffee
A founder-run Chicago cold brew company — small-batch coffee, cold-steeped and canned with nothing added. Zak and the Third Rose crew are the warm half of the ritual: when the colony climbs out of the lake, the cold brew is already waiting on the ledge.
- Chicago born and canned
- Small-batch cold-steeped cold brew
- Pouring at the ledge after the plunge
Coffee huddles are part of the ritual — the plunge wakes you up, the pour warms you back down.
