Perforated leather is much more comfortable than jackets with zippered vents when the weather heats up. You’ll appreciate the perforated leather panels which make up over half the surface area of this jacket. I’m a fan of jackets with this construction because the slightly stretchy material gives good freedom of motion and cuts down the overall weight of a sport jacket like this. The jacket shell is mostly leather with panels of abrasion resistant Aramid in non-critical areas. The Razor Jacket offers excellent impact and abrasion protection with thick leather construction and CE approved “GP” type armor.
