Be the one who always has the perfect drink ready.
The river doesn't wait for you to find your drink. Preload it, dial it in, float on.
River tubing has a way of separating you from your stuff. Not this time.
Cans float downstream, thermoses sink, and open cups lose the battle with the first set of rapids. The pnümix was made for this — fully waterproof and floats when full, so when it takes a swim (and it will), it comes right back to you. Your drink stays sealed, cold, and fresh from launch to the last bend, no matter what the river throws at it. Preload before you put in, dial in your strength on the float, and drink straight from the pnümix — no open cups, no chasing anything downstream. While everyone else is mourning their floating cans, you're already on your second round.

What ships when
Available Accessories
The Sling
On the river, anything that isn't attached to you is eventually a gift to the current. Sling your pnümix over your shoulder or clip it to your tube handle — either way, it's staying with you through every rapid, every spin, and every moment you forget you're supposed to be holding on. Less chasing. More floating.
Extra Magazines
The river doesn't stop for refills. Neither should you. Load up extra magazines before you put in and you've got multiple drinks ready — each stays sealed and fresh until you're ready, so your last drink is just as good as your first. One river. Multiple drinks. Zero trips back to the car.
On-The-Go Tumbler Set
Stainless steel cups sized for sharing — because sometimes the occasion calls for a proper pour. No ice required — what's already coming out of your pnümix is ice-cold, so at 4oz a pour, refills take seconds.
Head Unit Carrying Case
The head unit stays on your magazine all day on the river — but once you're back on shore, it needs a place to land that isn't the bottom of a wet bag. The case keeps it protected, dry, and ready for the next float — not rattling around in your car or turning up mysteriously damp a week later. Because the river already took enough from you today.
