I bought this to replace my 16 year old Alpinestars Dyno jacket. I bought this jacket in all black with the goal of a jacket with sport cut/protection with a minimum of branding/flash. The EU 48 fits me perfectly at 5'9, 145 (I wear a 38" suit jacket). The stretch material is great and overall the jacket feels lighter and more flexible thanks to the stretch and thinner armor. This is my first perforated jacket and the extra airflow is a plus. Construction quality feels high and I'm very happy the jacket overall.
