    Key features

    What makes it work.

    Krypto Knee Padz

    Reinforced knee panels add protection and durability through a high-wear area while maintaining flexibility.

    UltraFlex Neoprene

    UltraFlex neoprene provides stretch and flexibility to help you move naturally and comfortably in the water.

    Wind-Resistant Smoothskin

    Smoothskin panels help reduce wind chill at exposed areas for greater comfort in cooler conditions.

    Strategic Seam Placement

    Strategically positioned seams support movement and comfort while reducing irritation in key areas.

    Adjustable Collar

    The adjustable collar lets you fine-tune the neckline for a closer, more comfortable seal.

    Flatlock Seams

    Flatlock stitching creates a durable, flexible seam construction suited to warmer-water use.

    Fit & sizing

    Find your right fit.

    Check the fit notes, size guide or dimensions before ordering. Sizing can vary by brand, style and intended use.

    How it should fit

    For the correct height you should measure from the top of the head all the way down to your toes.

    To get the correct chest measurement, you should measure across the widest point around your chest.

    For the waist measurement you should go from the belly button line around the body.

    It is important to remember that a wetsuit should feel quite snug on your body (as close to a second skin as you can handle) - Do not worry, they will give slightly over time!

    The most important place to get correct is around the core of the body. Focusing on the chest and shoulders.

    If the suit is too big it will flush with water, so it is important to make sure you get the correct size.
