English Channel Swimmer Badge
As it has always been, the badge that a Bluetit gets after their first swim is free. It's our gift to you to remember the experience, and so fellow Tits all around the world can give one another the nod when you spot that now-famous badge.
Now we have a whole host of other badges, from those to mark a specific achievement to those that mark you out as a certain kind of Tit.
This English Channel Swimmer badge speaks for itself. Fair play!
