Coat construction

A coat garment having semi-detachable sleeves and pocket means for receiving such sleeves in their semi-detached condition; the sleeves having essentially longitudinal, selectively openable seams for accommodating arm removal from such sleeves even while the coat is worn; the sleeves can then be tucked into the pocket means provided, preferably in storage pouch means provided by the back of the coat proximate the sleeve openings, so that these sleeves may be stored, and all of this without necessitating coat removal, whereupon the user enjoys the warmth of the body of the coat without encumbering his arms by sleeves; such sleeves being constructed for easy withdrawal and reinsertion of arms therein prior to reconstitution of the sleeves as respective arm coverings.
