K2's Sideshow is an all mountain ski designed to perform best for people who ski more in firm snow than soft.  Its 30% rocker will improve turn initiation while the 70% camber will improve rebound and edge holding ability.  K2 calls this its "All Terrain Rocker" offering versatility and ease in all snow conditions.

What is Progressive Sidecut?  "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." - k2skis.com

But what happened to Giro?  Nothing, we are still stocking commuter-specific Giro and Bell helmets.  We chose Lazer for our performance mountain and road line of helmets because of some of the awesome features they offer.  Big on the list is the Lazer Rollsys© wire retention system.  The retention system is the fitting device that gives helmets a custom fit by snugging it to your head.  Lazer Rollsys© provides a smooth adjusting interface in contrast to other ratchet-based retension systems.  High end models like the Lazer O2 and Oasiz come with anti-microbial, temperature regulating X-Static© paddings.  Read more at http://www.lazersport.com/index.php
