Per the title - If anyone has an extra race foam hump that they don't need, and would be willing to part with - would you please let me have it? (Need it for a resurrected jacket) PM me the price / shipping charges to 26104 etc. (paypal) Thanks in advance.
I suggest you go to your local supply store that sells foam for replacing seat cushions and buy a block of foam for a few bucks. Then cut and shape with a bread knife. The chances of getting one the right shape from someone are slim or none and I think slim just saddled up and left town.

Interesting read! Never did think of it as protection. My street riding jackets don't have them/ I do wear CE certified back protectors. However, the new jacket was salvaged from a crashed suit, and so it has the compartment for the air hump. I'd rather it not flop while I'm riding. Probably look for something softer / lower profile. In any case, I appreciate the input.
