What is a vent?
A 17. Vents are openings on the back of the jackets. Some call it slits. Classic traditional styles usually have one center vent at the back of the jacket. Very traditional British or 50s and 60s style of jackets have two side vents at the back of the jacket and more modern ´Italian cut´ slim styles have no vents at the back of the jacket in which case the hips tend to be a bit on the snug side as well.
