Surf Bucket Hat with Chin Straps for Surfing, SUP, and Watersports

Do you think this will fly off on a roller coaster?

I measured the around my head and it is 23,2" inches, should i go with the M or the L? Thanks

I bought the medium but the fit is too small. i tried a friends large and that fit well. can i exchange it it for a larger size.? it hasn't been used

Why only black?
