Alpinestars Nucleon KR-2I Back Insert - Black
Customer Product Reviews
Comfortable, protective back armour.
Another great product from Alpine stars. I feel much safer with added back protection, it doesn't compromise comfort of my Alpinestar jacket and it slips easily and securely into the provided pockets of my jacket. I would recommend this product.
Perfect light weight
So I purchased for my new light weight breathable jacket, perfect combo. Just wanted to add extra protection. Very flexibly comfortable and light. I purchased a medium for my 2xl Alpinestar viper v2 jacket and fits perfect. Definitely recommend.
