Instead of last year's three series, K2's ski range for the season 2009/10 is divided into four series. This had been done by the separation of allmountain and freeride models, while the T:Nine and Factory series continue to exist. As already known, K2 puts emphasis on the skis for all terrains with everything, except dull design.

Freeride skis represent the new Adventure series with thirteen models and only one of them, Pontoon, same as the previous season. All models have cores containing light paulownia wood. Tip and tail holes function as a skin attachment points when heading up the mountain or facilitate building a rescue sled. Three "side" models, Darkside, SideStash and HardSide (left) are pure freeride models with a waist width of 98 to 128 mm and tips lifted off the ground to eliminate hooking on piles of soft snow. Coomback model is a dedication to the deceased D. Coombs and a bit gruesomely sounds the fact that the second famous K2 promoter, S. McConkey, also died recently. He developed the Pontoon model. The rest of the Adventure series consists of the so-called "back" models: Backlash, WayBack, Backup, BackLife and BackOut. With them, the Americans fulfilled touring skiers wet dreams. Lightweight, with 72 to 92 mm waists, they are an excellent choice for all adventurers who use their own strength to conquer the mountain up and downhill. Adventure series is rounded with three female models: GotBack, Payback and She'sBack.

Apache series (headline photo) in the season 2009/10 contains pure allmountain skis for skiers who prefer ski resorts better than snowbowls. Such models should find themselves familiar with crud, powder or groomed snow, equally. Waist width of Apache series' skis is between 68 and 84 mm and all models have built-in MOD technology. "Green menace", MSL model, is a great carving tool for groomed slopes and somewhat wider Crossfire is a great choice for an allmountain ski that advanced intermediates can enjoy. Stinger or Force model with its average 14 m radius and Catch Free technology (more about it here) are good choice for beginners.

Special attention has been given to female skiers who can choose one of seven models in the T:Nine series. Special core, bindings, use of bamboo and paulownia as light and fast growing (and environmentally conscious) wood, 2 cm forwardly pushed bindings..., these are all ideas for making skiing an easier sport for the ladies. Noteworthy is a fact that a part of the income of the T:Nine series is donated for breast cancer research program. With 70 to 82 mm waists purpose of these skis is similar to Apache series – to meet the requirements of the different types of surfaces. Advanced skiers who prefer deep snow will select a Lotta Luv model, while those of equal technical knowledge, but focusing on the groomed slopes will choose Burnin' Luv (right). On the other side of the series are First Luv or Sweet Luv models for beginners and intermediates.

Factory models are designed for acrobatic stunts in snowparks and also allow some offpiste adventures. These twin-tip skis are characterized by thick, 3.5 mm steel edges and tips and tails reinforced by rivets. Rocker design means that the tips and tails are significantly lifted off the ground and contact point of the ski and the snow is much closer to the binding. Schizofrantic inserts, introduced this year, are a preparation for mounting Marker bindings. Graphical design is a reminiscence of street art. Skis like Hellbent and obSethed are primarily for deep snow, while Ext and Disorderly are intended for snowparks.
