  • Wetsuit Sizes

    Wetsuits

    Different wetsuits have different fits.

    Thanks to the high elasticity of the materials, the more flexible wetsuits adapt better to the swimmer’s body than those with less elasticity.

    If you’re choosing a wetsuit with less flexibility, you should select a size that fits well to your body.

    At Orca we always recommend trying the wetsuit on to make sure that the fit feels right. However, should you have any questions, contact us and we’ll be happy to help you.

    One piece wetsuits

    When selecting the ideal wetsuit size, three measurements should be taken into account: chest circumference, height and weight. When in doubt, we recommend choosing the size that best fits your chest circumference, since it is important that the wetsuit is well- fitted in this area.

    For children’s sizing, the measurements we will look at are the chest circumference, waist, hips and height. When in doubt, go by the chest circumference in this case as well.

    Two piece wetsuits

    To determine the ideal size of a two-piece wetsuit, four measurements should be taken into account: chest circumference, waist, height and weight.

    Tops

    The chest circumference, height and weight help to figure out which size top will fit best. When in doubt, the chest circumference should be the most closely fitted.

    Bottoms

    When selecting your size, your chest, waist and hip measurements should be referenced. Don’t forget that each range is different and has a different elasticity, compression and pattern. To ensure a better fit, Orca has developed its own size chart for garments in each range.
