Breathable When Dry. Inflatable When Wet.

Every Wailana™ is powered by Dualfactor™ Technology, our patent-pending buoyancy system: a chamber in the chest, filled through a tube at the collar. No CO₂ cartridges, no hardware, nothing to replace.

See the chamber inflate, float and deflate — in real water.
  1. Step 1: Get it wet

    Your Wailana™ must be wet before inflating. Once wet, you can inflate in or out of the water.

  2. Step 2: Blow to inflate

    Find the tube inside your Wailana™ and blow into it like a balloon. Inflate to your preferred level of buoyancy.

  3. Step 3: Fold & secure

    Fold the tube over and secure it with the attached strap.

  4. Float & have fun!

    Relax, float and enjoy the water.

  5. Step 4: Unstrap & lift

    Release the strap and lift the tube beside your head, keeping the opening above the water.

  6. Step 5: Press to release

    Hold the tube up and press the inflated area with your other hand to release the air.

  7. Deflates as it dries

    Your Wailana™ also gradually releases air as the fabric dries.

Why it's different

One shirt instead of two pieces of gear.

Most water wear does one thing well. We think it should do more.

Mawowui™ is a water wear brand built on a simple belief — the gear you wear in the water should work as hard as you do, quietly and without getting in the way. Our first product, Wailana™, builds a buoyancy chamber directly into a performance rash guard, debuting in the Mauka Collection. It's where we start. Not where we stop.
