A tubular sleeve comprising: a cylindrical wall extending axially from a proximal end to a distal end, the cylindrical wall having an inner surface enclosing an interior volume and an outer surface opposite the inner surface; a cutout extending through a portion of the cylindrical wall from the outer surface to the inner surface, proximate to the distal end, the cutout defined in part by a first cutout edge and a second cutout edge, wherein the first cutout edge is positioned across the cutout from the second cutout edge; a first panel spanning the cutout and having at least a trailing edge, a first side edge and a second side edge; a second panel spanning the cutout and having at least a leading edge, a trailing edge, a first side edge and a second side edge, the second panel affixed to the tubular sleeve such that the leading edge of the second panel overlaps the trailing edge of the first panel and defines at least a portion of a distal thumbhole; a third panel spanning the cutout and having at least a leading edge, a first side edge and a second side edge, the third panel affixed to the tubular sleeve such that the leading edge of the third panel overlaps the trailing edge of the second panel and defines at least a portion of a proximal thumbhole; and a mitten affixed to the inner surface proximate the distal end of the tubular sleeve, wherein each of the first side edges (1018, 1028, 1038) of the panels (1012, 1022, 1032) are affixed to the tubular sleeve at a first seam and each of the second side edges (1020, 1030, 1040) of the panels (1012, 1022, 1032) are affixed to the tubular sleeve at a second seam, wherein the first seam and the second seam are configured to join the panels (1012, 1022, 1032) to the tubular sleeve at the first cutout edge and the second cutout edge. a cylindrical wall extending axially from a proximal end to a distal end, the cylindrical wall having an inner surface enclosing an interior volume and an outer surface opposite the inner surface; a cutout extending through a portion of the cylindrical wall from the outer surface to the inner surface, proximate to the distal end, the cutout defined in part by a first cutout edge and a second cutout edge, wherein the first cutout edge is positioned across the cutout from the second cutout edge; a first panel spanning the cutout and having at least a trailing edge, a first side edge and a second side edge; a second panel spanning the cutout and having at least a leading edge, a trailing edge, a first side edge and a second side edge, the second panel affixed to the tubular sleeve such that the leading edge of the second panel overlaps the trailing edge of the first panel and defines at least a portion of a distal thumbhole; a third panel spanning the cutout and having at least a leading edge, a first side edge and a second side edge, the third panel affixed to the tubular sleeve such that the leading edge of the third panel overlaps the trailing edge of the second panel and defines at least a portion of a proximal thumbhole; and a mitten affixed to the inner surface proximate the distal end of the tubular sleeve, wherein each of the first side edges (1018, 1028, 1038) of the panels (1012, 1022, 1032) are affixed to the tubular sleeve at a first seam and each of the second side edges (1020, 1030, 1040) of the panels (1012, 1022, 1032) are affixed to the tubular sleeve at a second seam, wherein the first seam and the second seam are configured to join the panels (1012, 1022, 1032) to the tubular sleeve at the first cutout edge and the second cutout edge.
