zinc oxide for me.
Im starting to think maybe blue for my nose( to match my shoes!)

Also,no toxins. Safe for enviroment, wont hurt kiddies if they eat the tube and washes out. No smell either.
So it looks funny, but then again,so do I! Cycle muggles are the only people laughing anyhow. Besides what goes so well with a duck walk( road cleats, chamois) , nappie( diaper) bum, eyestrain( logos and fluro tops) and general star wars clothing?! Coloured zinc!!
( you really know you a cyclist, when you see the opposite sex kitted up in this way, and you still think wow! sex on wheels.....)
