Sport neck guard with vertical fasteners and fabric fold to protect against cuts and lacerations

A neck guard for protecting a wearer's neck and throat from injury, comprising:

• a continuous, slash-resistant tube defining an inside, an outside, a contoured top edge, and a bottom edge and sized to receive a wearer's head through the inside and configured to be positioned around the neck of the wearer, the tube comprising knitted material in a high-strength textile fiber configured to form a series of vertically stacked grooves, pleats, ribs, or indentations encircling a wearer's neck when worn that allow the material to fold, bend, compress, and stretch ergonomically when the wearer's head moves throughout its entire range of motion;
• and
• means for vertically removably securing the tube to another device comprising at least a first and second strap extending from opposing sides of the bottom edge of the tube and configured to secure to a garment or accessory worn on the wearer's upper body or torso;
• wherein a front portion of the top edge defines a cutout shaped to follow contours of the wearer's jaw, and a rear portion of the top edge is relatively higher than the front portion and rises to cover a base of the wearer's skull when worn.
