I'm 6ft tall. I wear a large jacket so bought the medium size recommended. The fit is perfect and hardly noticeable when riding. Bikebiz shipped fast. Highly recommended. Thanks guys!
Very good as always
Back protector is comfortable and flexible, you don’t even notice it is there while gaining extra protection!

Hello Mohannad, Thank you for the excellent rating! We are thrilled that the Alpinestars Nucleon KR-1 Celli Insert Back Protector fits you perfectly. Looking forward to seeing you again! The Bikebiz Team
I bought size large as my Alpinestars jacket is a size XL. Fit perfectly. It also fits perfectly in my Motodry and Berik leather jackets. It is CE level 2 but is not thick and heavy. Its quite thin and light. Its getting warm where I live but you won't notice it and it doesn't make me sweat or hot. Very happy with this product.
Excellent service speedy postage will be back
