How to Measure for an O'Neill Wetsuit Cap

Head: Wrap a flexible measuring tape around the widest part of your head, above your eyebrows and ears. Keep the tape level and comfortably snug.

Neck: Measure around the base of your neck without pulling the tape tight.

Fit tip: A wetsuit cap or hood should fit snugly without uncomfortable pressure. If your head and neck measurements fall into different sizes, check the specific product's fit guidance before choosing.
