Surf Skull Sizing Guide
Get the right fit for your Surf Skull gear. Whether you are grabbing our classic V1 bucket hat helmet, the streamlined V2, or some fresh threads, use the guides below to find your size.
How to Measure Your Head
For the best fit, we recommend measuring your head before ordering.
-
Get a soft tape measure. (If you don’t have one, use a piece of string, then measure the string against a ruler).
-
Wrap it around your head. Place the tape just above your eyebrows and ears—the widest part of your head.
-
Keep it level. Ensure the tape is snug but not too tight.
-
Note the measurement in centimeters (cm) for the most accurate sizing.
Pro-Tip: If you are between sizes, we generally recommend sizing up for comfort, especially if you sometimes wear a hood underneath.
