The Free Speech Exerciser Bib is a wearable protest sign made from a Tyvek envelope, designed by Paradoxy Products' Daniel Young. Simply add your own message to the front, cut to fit and wear...

The bib has room for hands-free messaging on one side, while on the reverse it proclaims that – presumably with a US wearer in mind – "free speech is our 1st Amendment right".

Young says he designed the reusable waterproof bib after observing the signage problems faced by Occupy demonstrators in New York who were often reduced to writing their messages on cardboard.

Bibs cost $2.50 each (or $1.25 each for non-profit organisations), are shipped for free, and can be ordered from paradoxyproducts.com.
