you can get hard hat sort of baseball cas from b&Q. bump caps i think theyre called
I wear one of them over Paignton when I'm up on some high roofs where seaguls are nesting. Have to fend off the birds from attacking me with my wfpole from time to time. Every now and then there is a big culling on the seagulls around here as it can be quite dangerous when the seagulls dive bomb at you, hence a hard hat at times. It's essential at times.
really reminds me of a time when a new lad was working and got on to a penthouse balcony then the gulls started dive bombing him. he was scared stiff and started banging on the windows shouting "let me in you barstools I'm being attacked" we were rolling up!!
back to the subject of caps seriously guys cap's with work logos look really professional but sport teams are a BIG no no. you might as well where a shell suit to work.
