So, I finally took the plunge and spent some dollars on a leather jacket. The poorly fitting textile one I got with my first bike needed to go. I ended up picking up a black Alpinestars Indy jacket. I was interested in upgrading stock fitted back insert with the Alpinestars Bio Back Protector: http://www.alpinestars.com/Bio_Armor_Back_Protector/pd/c/170/np/170/p/6501611.html Unfortunately, i can't locate anywhere in Australia that stocks it. Was wondering if anyone has seen it around. Also, if i got a size 58 jacket, any idea how i figure out what size insert i need?
