The Austrian military M65 jacket is a type of military jacket worn by soldiers in the Austrian Armed Forces. It is modeled after the U.S. M65 field jacket, which was first introduced in 1965 and widely used by the United States military during the Vietnam War. The jacket typically made of a heavy-duty cotton or cotton-polyester blend, which is designed to withstand the rigors of military use. It's usually in olive color, which is intended to provide camouflage in a variety of environments.

The jacket features a button-up front and a stand-up collar, with adjustable cuffs and waistband. It typically has several pockets, such as chest and hip pockets, with button closures that can be used to hold various items and equipment, such as personal items, tools, and ammunition. The jacket can also be equipped with a detachable liner, typically made of wool or fleece, for extra warmth in cold weather conditions.

The M65 jacket is a classic and timeless design, and it's popular among military personnel, as well as people who like to wear vintage or military-inspired clothing. It could be also popular in some civilian uses such as hunting or hiking, for the durability and comfort that it provides, as well as its camouflage style that can be used in the outdoors.
