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 of the panels are affixed to the tubular sleeve at a first seam and each of the second side edges of the panels are affixed to the tubular sleeve at a second seam, wherein the first seam and the second seam are configured to join the panels 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 of the panels are affixed to the tubular sleeve at a first seam and each of the second side edges of the panels are affixed to the tubular sleeve at a second seam, wherein the first seam and the second seam are configured to join the panels to the tubular sleeve at the first cutout edge and the second cutout edge . <EOS>
