What do people use to cover up from the sun?
I have a skin condition that reacts to the sun and need something to cover up on the beach/in the pools/splash park etc on holiday.
Don't want to spend lots as will only need it one week a year.
Have never really done beach hols so am a bit 
Do only kids wear rash vests?
Ideally I'd just stay in the shade but I have a 5 yr old who'll want to play...
