The present invention relates to a tethering device for snowboard, comprising: a housing; a tether adapted to be accommodated in the housing, the tether having a first end connected to the housing, and a second end extendable away from the housing; an engaging means arranged at the second end of the tether, the engaging means having a receiving portion receivable at a guide portion of the housing; wherein the receiving portion is profiled to conform with the guide portion such that, the receiving portion, when arranged to be received at the guide portion, is positioned in a predefined orientation.

A ski may define a body that defines a tip, a tail opposite the tip, a top sheet, a base extending from the tip to the tail and opposite the top sheet, a core layer positioned between the base and the top sheet, and a reinforcement layer positioned between the top sheet and the base. The reinforcement layer defines an aperture extending through the reinforcement layer and positioned within a first third of a length of the ski, the length defined from the tip to the tail.
