K2 Protohype Snowboard 2012

K2 Shop all K2
The hype machine has been working overtime on this one and K2’s development team has delivered. The K2 Protohype Snowboard lets loose with the latest in a long line of top-end tech-focused boards. The Protohype is designed for the freestyle technician that demands the leading edge of technology in one super damp, clean design.
Construction and Core
The Bambooyah™ WH5 core is a skate style horizontally laminated bamboo core that is indestructible and sustainable. This is the best performing and lightest weight core in the line.
Harshmellow™ tech for a vibration force field that shields you from negative vibes, leg burn, and rough landings.
Ollie-Bar™ solves the concern over loss of pop when switching from camber to a flat base. It’s a carbon element that lives in the center of the board and is molded in place pre-loaded with camber.
Twin Hyper Progressive shape offers an infinite number of different radii that are blended together flawlessly from mellow in the tips, to more aggressive in the center. The result is a predictable feel that never hooks.
The Sintered Base is ultra-thin, static eliminating, lightweight, lower material usage, and the highest quality sintered base available.
Demanded by the K2 International Pro Team, K2 pioneered the Flatline® base profile. Preloaded, stable, and turn-ready, Flatline® is exactly as sounds - a flat base, and creating a supremely balanced, smooth ride for both aspiring and accomplished pros.


  • Terrain: All-Mountain, Freestyle
    All-mountain snowboards are designed for exploring the whole mountain. They are your go-to for a snowboard that will do anything. They feel at home on groomers, powder, park runs and almost anything in between. The vast majority of snowboarders choose all-mountain boards for their great versatility. If you’re just getting started or unsure of exactly what you need, an all-mountain snowboard is a great choice.
    Freestyle or park snowboards tend to be a bit shorter in length and love terrain parks, rails, jibs, trash cans, tree trunks, riding switch (non-dominant foot forward), wall rides and more. Freestyle boards often feature a true twin shape, and are typically selected by those looking to ride the terrain park. A more versatile variant of a freestyle board is the all-mountain freestyle, which combines the versatility of an all mountain snowboard with the playfulness of a freestyle snowboard.
  • Ability Level: Advanced-Expert
    Whether you charge the steepest lines, carve with race-like precision, hit the biggest jumps or halfpipes; advanced to expert level skis/snowboards are for the more aggressive rider. You will often find the addition of layers of metal, carbon, bamboo, or other stringers in these. These features work to make a stiffer ski/snowboard with more power and rebound.
  • Rocker Type: Flat
    A flat profile is just as you’d expect – flat from near the tip of the board to near the tail. This shape splits the difference between camber and rocker, with more forgiving turnability than a fully cambered board and more precise edging capability than a fully rockered one
  • Flex Rating: Medium
    The amount a snowboard flexes varies significantly between boards. Snowboard flex ratings are not necessarily standardized across manufacturers, so the flex may vary from brand to brand. Many manufacturers will give a number rating ranging from 1-10, 1 being softest and 10 being stiffest. Here at evo we have standardized the manufacturers' number ratings to a feel rating ranging from soft to very stiff. Generally you will find flex ratings of 1-2 as soft, 3-5 as medium, 6-8 as stiff, and 9-10 as very stiff. Flex ratings and feel may ultimately vary from snowboard to snowboard.
  • Core/Laminates: Bamboo
  • Warranty: 5 Years against core breakage
