Description & Specs

The Backup is the most efficient, technical ski mountaineering tool in the collection. Two sheets of metal give it a power and dampness not found in its weight class, and when combined with the 82mm waist, it skins hard, bony terrain with complete confi dence. The slight, All-Terrain Rocker aids trail breaking, takes the edge off sastrugi and other demanding backcountry conditions.

Durable and lightweight “cap” skis are built by a sophisticated molding process that envelopes the core and internal materials with the top layer of the ski. Used throughout our ski line, cap constructions can be assembled with a variety of different cores. These variations, such as glass and/or metal materials, are the determining factors of the skis’ performance.
Built from the base up, a metal laminate construction consists of alternating layers of fiberglass and titanal above and below the core. Metal Laminates provide damp, accurate, unshakable performance, ideal for expert and advanced level skiers.
A secure, self-centering attachment that reduces weight and allows for quick transitions on the ascent.
The new freeride tip and tail grommets are a clean, simple design that no longer requires a plug. The durable rubber coating disguises a slit designed to accommodate both the Z clip for our skin attachments, and the components to build a rescue sled.
Since snow collecting on the ski can add pounds to a climb, our SnoPhobic tops keep you light with a new snow-repellent topsheet. The running surface along the bottom of a ski is hydrophobic by design, so we’ve developed a thinner version of the same material to use on the BackSide model-specific topsheets.

    Comments about K2 Skis BackUp:

    I have used these skis for 2 seasons both in Austria and New Zealand. Best skis I have ever had. So good I bought a second pair! Great when the snow is crusty and chunky and fat enough to float in powder. An all round ski touring weapon!
