Abstract
A piggy back ski (10) comprises a first ski section (12) secured to a second ski section (14) by a plurality of releasable fasteners (16). The first ski section (12) includes a foot binding (18) secured thereto. The second ski section (14) can be selectively disengaged during skiing to permit continuation on the first ski section (12). If desired, a releasable fastener (34) can be used to prevent disengagement of the ski sections (12, 14) during skiing.
