A nose clip and a tail clip for a splitboard ski assembly may each comprise at least three hooks. The nose clip and the tail clip may be adaptable to various splitboard ski designs. A stretcher for a skin assembly may be configured to interface with the tail clip. The tail clip may comprise at least two elongated apertures defining a rail. The stretcher may be configured to interface with the rail via friction and/or secure a skin assembly to a splitboard ski assembly.

A personal self-propelled vehicle for travelling on snow using ski comprises a closed-loop flexible ribbon configured to envelope the ski over its length so as to pass under at least a portion of a sliding surface, two rollers and configured for installation on longitudinally opposite ends of the ski and to interact with the ribbon. The roller is a driving roller and is engaged with a motor comprising a control means and with the ribbon to transfer force for translational movement thereof. The roller is a guiding roller. The ribbon canvas has multiple via openings divided by webs and substantially constitutes a lattice. Dimensions and positions of the openings and parameters of the webs between them are selected so the sliding surface of the ski abuts on snow through the openings during motion of the vehicle, while the webs sink in snow under load of the vehicle bearing the user and provide repulsion from snow packed by the ski, thus assuring the ski sliding in longitudinal direction.

A climbing aid for a ski has a plane base element which is connected on the inner side to a fastener to be detachably fastened to a running surface of the ski and which is connected on the outer side to backwards-slipping prevention elements acting contrary to a direction of travel. A flexible plastic support material forms the base element, and the backwards-slipping prevention elements are integrally formed with the plastic support material. In lateral regions, the base element has backwards-slipping prevention elements with push-off wings positioned obliquely to the direction of travel and, in the central region, has backwards-slipping prevention elements with push-off wings arranged substantially perpendicular to the direction of travel. The push-off wings of the backwards-slipping prevention elements of a first type are of lesser length and/or of lesser height than the push-off wings of the backwards-slipping prevention elements of a second type.

An improved system and method for keeping articles of clothing properly fixed in place. Embodiments include a first portion and second portion of the clothing. Embodiments further include climbing skin having a plurality of fibers affixed to the first portion. The climbing skin fabric having a plurality of fibers allowing movement of the second portion in one direction with respect to the first portion while impeding movement of the second portion in the other unwanted direction.

Provided herein is a composition for improving performance of waxless skis, in particular skin skis, more particularly of skin strips, on snow, the composition comprising (a) C.sub.1-6-alcohol(s); and (b) lubricant(s) selected from a group consisting of (c) perfluoropolyethers, (d) polydi(C.sub.1-3-alkyl)siloxanes, and mixtures thereof.

An improved system and method for keeping articles of clothing properly fixed in place. Embodiments include a first article of clothing and a second article of clothing. Embodiments further include having one or more climbing skin fabrics having a plurality of fibers affixed to a first article of clothing. The one or more climbing skin fabrics having the plurality of fibers allow movement of the second article of clothing in one direction with respect to the first article of clothing while impeding movement of the second article of clothing in the other unwanted direction.

Provided herein is a composition for cleaning skin strips of skin skis, in particular for removing hydrophobic compounds, such as oils, resins, grease, and/or waxes, from the surface of the skin strips. The composition comprises (a) C.sub.1-6-alcohol; (b) at least 10% by weight of the total weight of the composition of dibasic ester(s) of formula R.sup.1OC(O)(CH.sub.2).sub.nC(O)OR.sup.1, wherein n is 2 to 4; and each R.sup.1 is independently C.sub.1-6-alkyl, (c) 0 to 5% by weight of the total weight of the composition of alkoxyalkanol(s) of formula R.sup.2O(CH.sub.2).sub.mOH wherein m is 1 to 4, preferably 2 or 3, and R.sup.2 is C.sub.1-6-alkyl, preferably C.sub.3-6-alkyl; and (d) 0 to 5% by weight of the total weight of the composition of tri(C.sub.1-6-alkanol) amine(s).
