Solution Overview

Problem

Existing climbing aids for ski touring, such as climbing skins and plastic aids, face issues like high production costs, weight, and inadequate grip in varying snow conditions, particularly forming lumps or icing that hinder ascent, and fail to provide sufficient support on slopes.

Innovation Solution

A climbing aid featuring a flexible plastic carrier material with anti-slip elements formed in one piece, designed with angled push-off flanks in lateral areas and perpendicular elements in the central area, reducing sliding resistance and ensuring adequate grip across different snow conditions, while being lightweight and adaptable to ski geometry.
