A jacket has several features useful for participating in a sport while wearing the jacket. The jacket may have a shell with a pocket in an upper region of the shell and a semi-rigid collar located in the pocket, wherein the semi-rigid collar is movable between a storage position wherein the semi-rigid collar is in the pocket and a use position wherein the semi-rigid collar is partially removed from the pocket. The jacket may also have a shoulder region with discrete areas of gripping material located on the shoulder region. The jacket may also have an inner core wrap having a perimeter, wherein a portion of the perimeter is removably attached to the outer shell that hugs the torso of a wearer. The jacket may also have a sleeve and a gusset formed on an outer surface of the sleeve by folding material forming the sleeve at an inner angle of the wearer's elbow, wherein the gusset unfolds and the sleeve lengthens when the arm of a wearer is straightened and wherein the gusset refolds and the sleeve shortens when the arm of the wear is bent.
