Abstract: The sports jacket comprises at least one a closable vent (2) in the forearm region (1) of each sleeve on that side which is determined to lie adjacent to the inner side of the forearm. The vents (2) are each equipped with a zipper. Inside the vents an opening is provided in the lining (7) of the sleeve covered with an air-permeable textile fabric (4). The opening may be framed by a spring-loaded ring profile, which keeps the opening open in its relaxed state and forces it into a slit by way of closing the zipper. Alternatively, said opening is framed by a straight, spring-loaded profile which keeps the opening closed in its relaxed state. By means of twisting a turn-lock fastener (5) with pulling cables, the top ends of said profile are being brought closer together to its bottom ends against the spring force, thus spanning the enframed opening.

Abstract: A garment that includes a right chest panel; a left chest panel; a back panel; and a collar coupled to the right chest panel, the left chest panel, and the back panel. The collar may include a collar zipper controlling access to a collar pocket, the collar zipper extending around at least 80% of an outer circumference of the collar; and a collar-side row of hood-connection zipper teeth positioned in the collar pocket, the collar-side row of hood-connection zipper teeth having a length that is at least 80% of a length of the collar zipper. The garment may also include a removable hood. The removable hood may include a hood-side row of hood-connection zipper teeth, the hood-side row of hood-connection zipper teeth having a length that is substantially equal to the length of the collar-side row of hood-connection zipper teeth.
