A shin guard sleeve, comprising: a sleeve constructed from a flexible material, having: a top edge and an opposite bottom edge, an outer surface and an opposite inner surface, an anterior portion and a posterior portion, an anterior portion length as measured from the bottom edge to the top edge proximate the anterior portion being less than a posterior portion length as measured from the bottom edge to the top edge proximate the posterior portion, the sleeve having a medial side edge comprising a medial apex and a lateral side edge comprising a lateral apex, the medial apex and the lateral apex being present in an unstretched state of the sleeve, wherein the medial side edge and the lateral side edge are affixed together to form a joining seam, such that the sleeve is able to form a volume suitable for receiving a leg of the wearer and encircle the leg of the wearer wherein when in an as-worn position on a user, the anterior portion is proximate a shin region and the posterior portion is proximate a calf region of a wearer, and further comprising a maintaining material for maintaining the sleeve in an as-worn position, wherein the maintaining material has a higher coefficient of friction relative to the wearer's skin than the flexible material of the sleeve. a sleeve constructed from a flexible material, having: a top edge and an opposite bottom edge, an outer surface and an opposite inner surface, an anterior portion and a posterior portion, an anterior portion length as measured from the bottom edge to the top edge proximate the anterior portion being less than a posterior portion length as measured from the bottom edge to the top edge proximate the posterior portion, the sleeve having a medial side edge comprising a medial apex and a lateral side edge comprising a lateral apex, the medial apex and the lateral apex being present in an unstretched state of the sleeve, wherein the medial side edge and the lateral side edge are affixed together to form a joining seam, such that the sleeve is able to form a volume suitable for receiving a leg of the wearer and encircle the leg of the wearer wherein when in an as-worn position on a user, the anterior portion is proximate a shin region and the posterior portion is proximate a calf region of a wearer, and further comprising a maintaining material for maintaining the sleeve in an as-worn position, wherein the maintaining material has a higher coefficient of friction relative to the wearer's skin than the flexible material of the sleeve. a top edge and an opposite bottom edge, an outer surface and an opposite inner surface, an anterior portion and a posterior portion, an anterior portion length as measured from the bottom edge to the top edge proximate the anterior portion being less than a posterior portion length as measured from the bottom edge to the top edge proximate the posterior portion, the sleeve having a medial side edge comprising a medial apex and a lateral side edge comprising a lateral apex, the medial apex and the lateral apex being present in an unstretched state of the sleeve, wherein the medial side edge and the lateral side edge are affixed together to form a joining seam, such that the sleeve is able to form a volume suitable for receiving a leg of the wearer and encircle the leg of the wearer wherein when in an as-worn position on a user, the anterior portion is proximate a shin region and the posterior portion is proximate a calf region of a wearer, and further comprising a maintaining material for maintaining the sleeve in an as-worn position, wherein the maintaining material has a higher coefficient of friction relative to the wearer's skin than the flexible material of the sleeve.
