Find your Wailana™ fit.
Wailana™ has a performance athletic fit — tailored, not tight, for all-day comfort in and out of the water. The Dualfactor™ chest panel adds a little structure, which the measurements below already account for. Every measurement is taken from the finished shirt.


- AChest / bust — across the chest from underarm to underarm. The chart lists the full circumference.
- BLength — from the front collar seam straight down to the hem.
- CHip (women’s) — across the bottom hem.
- DSleeve — from the collar, over the shoulder and down the sleeve to the cuff.
- EWaist (women’s) — across the narrowest point of the waist.
- Choosing your size — compare with a rash guard you already love — lay it flat, measure it and match it to the chart. Between sizes? Size up. Wailana™ has a performance athletic fit, so the smaller size can feel too tight — the next size up gives you room for all-day comfort.

Always deflate before taking it off.
Release the strap and lift the tube beside your head. Hold the tube up and press the inflated area with your other hand to release the air. It comes off much more easily flat.
