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 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.
The COOMBAck is the first of a three part graphic series, each celebrating a different era of Doug’s ski career. Coombs cut his teeth on the steep, narrow chutes of Bridger bowl, before moving to Jackson Hole to hone his technique. The 102mm waist and All-Terrain Rocker create a balance between float and agility reflective of Doug’s versatility, and make the COOMBAck equally adept making tram laps or climbing the Ford-Stettner route on the Grand Teton. K2 will donate a percentage of all COOMBAck ski sales to Doug’s family, and another portion of the proceeds will fund the American Mountain Guide Association’s Chad Vanderham Endowment, which is focused on improving guide education and safety.
The steeper and more technical the terrain, the happier the K2 Coomback. After all, it was named after legendary mountaineer and extreme ski pioneer Doug Coombs. The Coomback is solid and reliable in steep terrain, it powers through choppy conditions at speed, and it floats through the deepest of days. Seasoned veterans can use this as their go-to tool for exploring exposed chutes and no-fall first descents, and not-so-seasoned shredders can point this rockered mid-fat everywhere from the trees below the tram to skin-accessed pillow lines. Let's face it, the Coomback is infused with the versatile capabilities of its legendary namesake, and that sounds pretty good to us.
Designed for adventure-seeking powder hounds like legendary skier/designer Doug Coombs, K2's COOMBack skis deliver solid edge hold and stability at speed. Take advantage of the soft-snow and powder performance offered by the progressive sidecut and 102 mm waist, while the All-Terrain rocker gives you quicker turn initiation. Designed to highlight Doug Coombs career with a splash of Jackson Hole on the topsheet.

Skied all the K2s in the upper 170s but am unsure as to exact lengths. Skied the K2 line in the same vein that I skied the BD line, as I would as an end user in the backcountry. The Coomback was the best ski in the pack for hard snow performance and did very well in the soft stuff as well but I could see where a bit more width would help on deeper days (see the Backdrop writeup). They didn?t suffer much from deflection and I felt they were the right weight to eat up a lot of the variable stuff we were running into later in the test day. Felt very similar in construction to the BD Justice with similar flex so for me they skied very similarly. I?m not a huge fan of their skin system and they confirmed that its not a rebrand or anything like that, they are just making them (so its not like Coltex making Dynafit skins etc.) I could see the tip hole being useful for a rescue sled.
I demoed a number of skis in 2011-2012 season with the intent of using for both in-bounds and back country. The Coomback was the last I tried, purchased in spring of 2012 and will have skied more than 30+ days this season. There are better floating powder skis for deep, deep days. Better carvers for the groomers or ice. But as an all around, get it done, solidly built do everything on-off piste, mountaineer trek, crud buster with occasional bumps thrown in for measure - this is a fine ski.
I teamed with a Marker Baron and a Dynafit Titan boot which makes for a heavy tour but a solid ride on the down hill. If I ever pick up a tech binding, it will likely go on my Coomback and I'll put the Baron on a powder plank for deep days at the resort.
I'm 6'3" and wiegh 185. I chose the 181 because I like to ski trees and am happy with my choice.
