K2 Coomback Skis

K2 Coomback Ski: The K2 COOMBAck skis are designed with the spirit of Doug Coombs, versatile enough for heli or cat skiing, skinning, or taking the lift. The COOMBack balances the lightness desired in a skinning ski with the robustness of a ski you wouldn’t dream of hiking with, giving power and willingness to trek. Whether you throw on alpine, tele, or touring bindings, you can blast your descent. New this year is a Carbon Web that increases responsiveness without sacrificing its lightweight.
K2 donates a percentage of all COOMBack proceeds to Doug’s family, as well as to the American Mountain Guide Association’s Chad Vanderham Endowment to improve guide awareness, education, and safety.

Triaxial Braiding

Triaxial braiding consists of braiding fiberglass around a wood core to provide torsional rigidity for added control. Developed in 1988 by K2 engineers, the patented triaxial braiding machine interlocks strands of fiberglass around a milled wood core. While flex and torsion vary depending on the wood, Triaxially braided skis share the common traits of ease, forgiveness, responsiveness, and energy in both expert and entry level

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.

Snow collecting on a ski can add weight 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 Back model-specific topsheets. Applying wax to the topsheet increases snow shedding performance.

The tails of our Adventure skis are designed with a concave notch to ensure that the skin clip, regardless of size or skin brand, stays securely centered on the tail.

All Adventure skis come with flat tails, providing backcountry utility by allowing you to plunge the tails easily into firm snow.

Holes in the tip and tail are not only the attachments points for K2 skins, but they also fit the functional needs of a backcountry skier including the ability to build a rescue sled or construct various ski anchors. The holes are equipped with removable plugs.

For backcountry skiers conscious of their caloric and environmental output, our Adventure skis use a blended core of aspen, bamboo, and Paulownia, (a reforestation plantation tree similar to bamboo) that has consistent density, great strength-to-weight ratio, and fast-growth carbon-sequestration. The core is just one component of the ski, but the result is 15% weight savings over our traditional fir/aspen cores and a lessened footprint, reducing the impact of the ski on you and the winter world.

The widest point of a powder tip is 7cm back from the standard contact point. The design adds stability and predictability while skiing and is less likely to hook or grab in light crusts or variable conditions.

Progressive sidecut is a combination of two different radii, or sidecuts, that enhance the versatility of wider-waist skis. Standard sidecut theory is based on using a single radius. This works well on narrower skis, but becomes overpowering on wider skis, especially in variable conditions. The use of progressive sidecut on wider-waist skis guarantees improved turn initiation and hard-snow performance.

ROCKER: Easy initiation, versatility, agility.
CAMBER: Control, edge hold, rebound.
All-Terrain Rocker features an elevated tip for variable and soft snow performance, as well as camber underfoot for power, energy, and edge-hold in firmer conditions.
Simply put, All-Terrain Rocker offers versatility and ease in all snow conditions.
