First tracks every time.

 After two years of development, millions of vertical feet climbed, and countless struggles, challenges, and triumphs, K2 is claiming their new Ultrasplit Splitboard with Kwicker Technology is the lightest, fastest splitboard system in the world. After checking it out for ourselves, we're inclined to believe them. It's designed to showcase the new system that ditches the painstaking pins and bulky binding plates; when you put it all together, the integrated system is 3.9 pounds lighter than the industry standard setup and 50% faster to transition from walking mode to ride-ready. Soon, the only problem you'll have is how mad your buddies are that you always get to drop in first.

We'll get back to the revolutionary binding system in a moment, but first the board. The All Terrain Baseline profile is mostly flat for stability, with more rocker at the tip to keep you afloat in deep snow and less rocker at the tail to prevent wheelies when landing. The Ultrasplit uses K2's splitboard-specific Ultratech construction. This hybrid construction uses a half-height sandwich that's as tough and lightweight as we've seen; the unique sidewall shape is also designed to withstand the constant abuse unique to split boards, as the two 'skis' bang together and try to de-laminate each other. The Ultrasplit sheds even more weight by eliminating the topsheet, and the Bambooyah bamboo core is used for its high strength-to-weight ratio and its sustainability as a natural resource. Carbon Web II carbon stringers improve power transfer to make the board more responsive for greater control at high speeds; K2 finished off the recipe with the ultra-thin, low-static Ø sintered base.

What makes the board even more special is the new Split Track mounting; instead of rows of holes that you need to painstakingly line up with your binding, the twin channels make it fast and easy to set the angles on your Voile setup. Its pinless design is much more glove-friendly, so you don't have to deal with frozen digits in the backcountry. But where it really shines is with the new K2 Kwicker system. Essentially a step-in binding system re-imagined, it eliminates the need for separate bindings and binding plates. To strap in, you simply pop out the binding, click in with your Kwicker Stark boots (sold separately) and go. To speed up the transition process even more, the Ultrasplit includes Z-Clip notches at the tip and tail of the board that pre-cut skins (sold separately) hook into quickly and securely. It all comes together to create a better splitboard that gets you on the trail earlier, ready to ride more quickly, and more confident when you drop in.

Picked up the Ultrasplit this season and have already got quite a few days on it. The board is nice and lightweight, really like the shape and rocker profile. It rips in pow, amazing float and stability. Because of the low angle, gradual rocker the board planes in deep snow really well instead of just pushing it. I feel like this also gives much more power to the tail than most other boards i've ridden with rockered tails. Super fun setup that can really charge when I want to. Loving it so far!

this is not's fault, but I've had to return three of the boards - from a cracked topsheet near the tip to way to big of a gap between the splitboard halves (even with the bindings on). In fact, each board was worse than the previous. Seems like a production issue with K2. Glad you had good luck with yours, it looks a board with potential.
