In the Bag. Now with added protection.

Bhoffo over at the NSW Bandits forum suggested "You can get it in the form of place mats from those cheap shops (aka Go-Lo or similar) just cut it to the desired shape and use double sided tape to hold it in place on your straps.. "

I spent $4 on a roll of this gripping foam from Go-Lo today. Could have bought a Tank Blanket from a leading UK bike accessories maker for 5 times this price. I am such a cheapskate.
