The US Regulation Shell Jacket was worn by US Cavalry units throughout the war.

This US Shell Jacket is made from quality 16 oz Navy Blue wool and is trimmed in 3/8 inch Cavalry Yellow wool tape. The jacket has a 12 button front of Federal Eagle buttons. The button holes are HANDSTITCHED. The jacket has 2 button functional cuffs and 2 buttons on each side of the standing collar and saber belt bolsters on the back. The body is lined in brown cotton and the sleeves are lined in unbleached muslin. There is one inside pocket. The collar trim has double rows of tape. The collar, sleeve, front edge, bottom, back seams, and bolsters of the jacket are trimmed in tape. The bolsters are rolled.

The bolsters were set at the bottom of the rear/side seams and were designed to 'bolster' the weight of an artillery saber belt which carried the pistol and saber of a mounted soldier. The mounted services jackets are typically longer than most other Civil War shell jackets as the belt needed ride above the bolsters.
