Find Your Cap Fit

Not sure what size to get? The Coasta Cap features a stretch-fit construction designed to comfortably adapt to your head without a traditional back closure.

Size	Head Circumference	Approx. Fitted Size Equivalent	Best For
S/M	56 cm (approx. 22.0")	Approx. 7 – 7 1/8	Smaller to average heads or a snugger, athletic fit
M/L	59 cm (approx. 23.2")	Approx. 7 3/8 – 7 1/2	Average to larger heads or a more relaxed fit

Both sizes feature an elasticated internal knit headband and stretch performance fabric for a secure, comfortable fit that moves with you.

How to Measure Your Head

Grab a soft tape measure (or use a string and ruler).
Wrap it around your head where a cap would naturally sit — just above your eyebrows and ears.
Keep the tape comfortably snug without pulling it too tight.
Use the measurement in centimeters (cm) to compare with the size chart above.

Fit Notes from the WoBe Team

The Coasta Cap is designed differently from our full-brim hats. Its stretch-fit construction and elasticated internal headband allow the cap to adapt comfortably to your head while maintaining a clean, fitted silhouette.

If you're between sizes, go with your preferred fit:
→ Snugger fit = S/M
→ Roomier fit = M/L
