The s.LIGHT is the first avalanche backpack with the proven ABS® Twinbag System, whose base unit weighs less than 2 KG. This weight optimization, of course, does not mean a loss of safety or functionality. The s.LIGHT ZipOns allow a lateral ski attachment on the one hand and a snowboard mounting with specially adapted and developed snowboard straps on the other. The s.LIGHT also offers space for a drinking system, shovel and probe and a first aid kit. An ice axe can be attached to the ZipOn just as easily as a helmet with the help of the supplied helmet net. This item does not include trigger and canister.
