<p>A hockey goaltender's pad is described, in which the upper segment of each side roll is sewn with darts which facilitate flexing of the rolls. As the knee is bent, the darts open, thus in effect increasing the length of the outside of the roll in response to the tensile load there, so that the outside of the roll does not restrict the flexing. As the leg is straightened again, the darts close.</p> |
