Tinea is highly contagious.
I would not purchase used bibs for the same reason I would not purchase used underwear or socks or used mattresses. I hope whomever does washes them with bleach and puts them in the dryer on high for at least 1 hour to kill whatever pathogens might be present.
Back to the topic, the Romanian made Castelli Nanoflex bibs are
so comfy. I almost wish it would get cold.
