Thermal Overshirt Jacket is an hybrid garment that can be worn as a shirt or jacket. It is a hybrid garment that combines a shirt and hooded jacket. It provides warmth without adding bulk to a winter coat.

4. Snap or Button Closures

The majority of thermal overshirts jackets have button or snap front closures. This detail gives the jackets a shirt-like look while still maintaining their functionality.

5. Functional Pockets

Often, chest pockets and side pockets can be found. They are not only practical, but they also add to the style.
