K2 was established on Vashon Island, Washington in 1961 by the Kirschner brothers. It should come as no surprise that the company hails from Vashon Island, an outpost of free thinking and new ideas in Puget Sound. The company gained prominence when American ski racers Phil and Steve Mahre won World Cups, World Championships, and Olympic medals on the skis.
K2 is now based in Seattle, Washington and produces some of the most popular skis in the world. The men's Apache series and corresponding women's Luv series are the brand's expert level skis and are known for performing well under a variety of conditions with a lively yet predictable feel.
A note that will help many: In the past few years K2 skis have run long compared to other brands. In 2009 K2 fixed this be adding 3cm to the stated length of most of their skis while keeping the actual length the same. So a 2008 Recon in 167cm is the same length as a 2009 Recon in 170cm.

I had the pleasure of taking these skis out last this past Sunday, November 8 2009. I went up to Arapahoe Basin to get some early season skiing in. It was my first time out this season and after my first run two words came to my mind. Quick and Nimble. These skis were very responsive and super fun. Sharp quick turns were effortless at a moderate speed. Very Poppy. The skis really shined when I turned up the heat and tried some high speed GS turns. I would recommend this ski for anyone who likes to ski fast and carve hard on the groomers. I would also recommend going with a longer length. I enjoyed the 163's but when I really got then on edge and hauled they felt a tad bit unstable. I am 5'10" 165lbs.
