If we had to describe the Convertible Packable Mid-Layer Jacket in a single word, it'd be "Versatile." This layer gives you two-in-one style with the zip-off sleeves - one moment it's a jacket; the next it's a vest. And because the lightweight layer features body mapping stretch panels, this non-bulking gear layers effortlessly under a riding jacket for extra defense when the weather turns. The quilted 3M(TM) Thinsulate(TM) Insulation helps ensure comfort in the chilliest forecasts. Great on its own or under gear, this versatile men's casual jacket folds up so it's easy to tuck into a saddle bag "just in case."
