Tap to see how
Chest — Wrap the tape around the fullest part of your chest, keeping it parallel to the floor. Bring the tape under your armpits and across your shoulder blades. Don't pull too tight.
Waist — Find the narrowest part of your torso, usually just above your belly button. Stand naturally — don't hold your breath or pull in your stomach.
Hips — Stand with feet together. Wrap the tape around the fullest part of your hips and seat, parallel to the floor — usually about 8–9 inches below your natural waist.

Fit Tips for Diving

🇺🇸

Used to US sizing? Size up if between sizes

Our sizing runs slightly small for standard US size charts — we recommend staying true to size or sizing up if you're between sizes. We recommend a snug fit since polyester stretches out in the water.
🇪🇺

Used to EU sizing? Size down if between sizes

Our sizing runs slightly big for standard EU size charts — we recommend staying true to size or sizing down if you're between sizes. We recommend a snug fit since polyester stretches out in the water.
🤿

Stays put under your BCD

Our men's rash guards are designed to stay in place through multiple dives. Size to your chest for the best fit — the rash guard should feel snug enough to not ride up under your BCD, but comfortable enough to move freely underwater.
🩱

Layering under a wetsuit

A rash guard worn under a wetsuit reduces friction and helps the wetsuit glide on more easily. For layering, size true to your chest measurement — a close-fitting rash guard works best as a base layer under neoprene.
🔀

Which Measurement to Prioritise

If your chest, waist, and hip measurements suggest different sizes, always prioritise your chest measurement for a rash guard — it determines the overall fit across the shoulders, arms, and torso. The chart is the same wherever you order, and most people should simply take the size it gives them. The selector above only changes the call when you land between two sizes — set it to the sizing you normally buy.

Loving this gnarly octopus rash guard!

Loving this gnarly octopus rash guard! Have had a lot of comments in the lineup while surfing. I’m 6’ and 180lb and a medium fit me really well. Have got a second one now in a lighter colour to contrast darker shorts.
