I recently had to go on blood thinners (DVT plus two PEs) so head injuries are extra serious. Been surfing all my life but suddenly felt the need for head protection. This looks pretty good. It always feels a bit uncomfortable when I first put it on (59cm head, got a Large) but softens in the water. Duckdives are a biggie with a hat but so far it’s staying on. It feels a bit odd but overall it’s pretty good.
