Depends in the kid. Dd is a puddle jumper and soaks her trousers so I try and get her to wear her all in one. Hers is red and made by Muddy Puddles - I bought it from a farm supplies shop it wax quite cheap but v durable. If you go for all in ones size up as much as possible and have them baggy as they grew out of them fast I'd the zip goes down between their legs
