This replica of the M41 campaign jacket is made of cotton and has a flannel lining. It has, as originally, a zip and multiple plastic buttons to close but also multiple other buttons used for tightening sleeves, tightening the size or in the neck. This jacket is provided to all US Army personnel in combat and at rest. Presence of two side pockets in front of the jacket. Unlike the more economical version, this version is better, more thick and more resistant. The lining is superb and can wear the jacket upside down, as did some units in Normandy to improve their camouflage.
