Alpinestars Bionic Air Insert Men's Back Protector Street Racing Motorcycle Body Armor - Large

hope I never have to USE this but its great for riders.It made my jacket feel nice a snug against my body,It also gives me more confidence when riding.

Makes me feel like I will be safer if I take a spill. Also helps airflow and keeps the jacket from resting on my back.

fit perfect in my Alpinstars Verona Jacket size XXL. Perfect fit!reallt slim and lite! almost don't feel it in the back.

Great product, you hardly feel it in your jacket

i have the alpinestars tgp-r air jacket. the back insert was just a crumby piece of foam. I replace it with this. which is very sturdy and stiff. It can flex in one direction and isnt that much bulkier than the original foam inside the jacket.
