The Butterfly 2.0 Basket is a spare part, available separately. The basket consists of two parts one on top of the other so the basket surface adapts flexibly and quickly as needed to the terrain. With its patented, split design, the Butterfly 2.0 is the first ski touring basket that adapts perfectly to the slope’s gradient when traversing, and its surface area expands automatically under loads. You get optimum grip on any terrain, guaranteed. The constant adaptive movement of the two wings while moving prevents annoying, energy-sapping snow sticking to the bottom of the basket.
