So you have this bitchin old 3/4 with a blown lout liner and styromfoam that rattling around and fits so loose its like a sail choking the shit out of you at any speed above walking? Fear not, fellow collectors of old shit helmets. We just picked up some of these liners for the biltwell novelty helmets and in less than 10 minutes (most of which are spent deciding on sticker placement for your toolbox, bike, face, ect.) you can have yourself a like new lid again. Just strip it down to the shell (most helmets do this on their own) drop in the new liners and viola! Its like a hug for your head, a gentle soothing hug. Now you can fully enjoy your vintage tweeker 70's painted lid again. They also work for people who have stupid big heads like myself, with the styrofoam safety bit i can't fit into pretty much any old helmet that i own, maybe i just picked up a bunch of medium ones? who knows? Anywho, this is the ticket right here. Oh and its cheap, like 20 bucks kind of cheap. fuck yeah, thanks biltwell!
