Very good jacket in terms of construction quality, superior to other brands. Used on a naked bike. It doesn't have as good ventilation at low speeds or on hot days as jackets from other brands (e.g., Revit, Alpinestars), I assume due to the thick weave of the "mesh." At high speeds, its ventilation is very good. It falls into the abrasion category A (up to 45km/h) and has hard level 1 protections on the shoulders and elbows. The back protector is sold separately (it has 2 pockets that can accommodate back protectors: Pro Armor G1, Wave G1, Manis G1). It comes with a windproof membrane (not waterproof) for cool evenings or mid-season use. Short - mid-length with a very tight - fitted fit, especially in the arms and chest, while there is more room available at the waist. The Dainese size chart puts me at 44, but 42 is the one that fits me perfectly. A girl with a large chest may need to stick to the size suggested by the size chart. I recommend trying it on before purchase. The "mesh" fabric is much denser than other jackets in the same price category, and the polyester fabric is of different quality. Good construction regarding zippers, pockets (a bit small in size), the leather stitched logos, and the Velcro. It's worth the money as a jacket that will protect and last over time.
