Touring where it rains I put a Plastic bag on my Brooks ..

It seems the fabric went in the mold, 1st, the rubber next, then the whole thing is cooked (vulcanized) in the Mold..

Of course you can find them in the shops and feel the surface, in your hands for yourself..

Though probably have to get the streets plowed better first , a bit Snowy now I hear..
