Outdoor base layer including integrated knee protection
A base layer such as an undershirt or long underwear, for outdoor activities is described. The base layer includes an integrated joint protector. The protector includes foam padding realized as a collection of individual, mutually separated pads having a polygonal perimeter. The thickness of the pads decreases from a centerline of the protector to its medial and lateral edges. The medial and lateral edges have triangular individual pads with vertices facing out, which prevents binding or creasing of the protector under flexure.
1 . An athletic base layer garment comprising:
a garment comprising one or more elastic fabric layers, sized to fit tightly to a portion of the body of a wearer;
a padded joint protector integrated into a fabric layer of the garment over a joint of the wearer, wherein the padded joint protector comprises a plurality of individual, conformable pads mutually separated from adjacent pads by open channels;
wherein, the joint protector is a knee protector arranged over the knee of a wearer when the garment is worn;
wherein the joint protector comprises a center column of pads that cover a vertical centerline of the knee of a wearer, and wherein at least one pad in the center column of pads covers the wearer's kneecap;
wherein, the joint protector further comprises flanking columns of pads on either side of the center column;
wherein the joint protector further comprises medial and lateral columns of pads on either side of the flanking columns;
wherein the medial and lateral columns of pads include pads having a triangular perimeter; and
wherein the pads having a triangular perimeter are arranged with each pad having a vertex that points out in a medial or lateral direction relative to a vertical centerline of the knee protector.
2 . The garment of claim 1 , wherein at least some of the pads in the central and flanking columns have a polygonal perimeter.
3 . The garment of claim 2 , wherein at least of the pads have a triangular perimeter.
4 . The garment of claim 2 , wherein at least some of the pads have a quadrilateral perimeter.
5 . The garment of claim 1 , wherein the pads are attached to a common, flexible base layer comprising the same material as the pads of the joint protector.
6 . The garment of claim 1 , wherein the pads in the central column have a first thickness, the pads in the flanking columns have a second thickness, and the pads in the medial and lateral columns have a third thickness, and wherein the first thickness is greater than the second and third thicknesses.
7 . The garment of claim 6 wherein the first thickness is greater than the second thickness and the second thickness is greater than the third thickness.
8 . The garment of claim 1 , wherein the joint protector includes a lateral pad arranged on the lateral side of the knee when the garment is worn.
9 . The garment of claim 8 , wherein the lateral pad is arranged to be on the wearer's knee's bend axis when the garment is worn.
10 . The garment of claim 1 , wherein the joint protector is configured to taper in width from an upper side to a downward side.
11 . The garment of claim 1 , one or more of the elastic fabric layers includes one or more of the following materials: polyester, nylon, elastane, polypropylene, wool or silk.
12 . The garment of claim 1 , wherein the padded joint protector comprises one or more of the following materials: polyethylene foam, PVC foam, Neoprene, vinyl nitrile foam, silicone foam, polyurethane, open cell rubber, gels and non-Newtonian fluid cells.
