Product Details
Rocker Type
Twin Combination Camber Profile – The best of both worlds. By blending both traditional Camber and Rocker profiles, Combination Camber gives you all the benefits of both: the pop and precision of camber, and the float and predictability of rocker.
Flex
Flex Rating – 5 (1 Playful - 10 Precise)
Core
BAP Core – Bamboo. Aspen. Paulownia. K2 has blended three species of renewable timber to assemble a core that’s strong, lightweight, and designed to enhance dampening without the addition of other materials.
Laminates
Carbon DarkWeb™ – A carbon fiber X-pattern that is strategically placed underfoot from edge-to-edge to speed up transitions, increase control, and increase underfoot strength.
Triaxial Glass – A glass laminate with diagonal layers that adds torsional stiffness for increased stability and improved edge hold. The fibers three layers of fibers are woven at 45° , 45° , and 0° . This makes for a more responsive ride longitudinally and torsionally.
Base
Sintered 4000 Base – The sintered 4000 base absorbs wax deep into the material for relentless glide and unrivaled durability.
Additional Features
Hybritech™ Construction – Backed by years of rigorous testing, Hybritech is the lightest weight, most durable snowboard construction on the market. Removing excess sidewall material in the tip and tail and adding a 3D capped edge to increase the bond strength of the fiberglass and decrease the swing weight of the board is what makes Hybritech so revolutionary, helping K2 boards spin faster, maneuver easier, and last longer.

Terrain
Freestyle 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. All-Mountain 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.

Ability Level
Intermediate-Advanced Whether you’re a progressing intermediate exploring new runs and terrain, or an accomplished rider seeking new thrills, the majority of skiers and snowboarders fall into this level. Intermediate to advanced skis and snowboards may be somewhat wider or stiffer than beginner-intermediate skis and snowboards, usually with a stronger wood core and sandwich sidewall construction. Intermediate to advanced boots and bindings range from softer flexing freestyle options to stiffer choices built for stability at speed.

Rocker Type
Rocker/Camber/Rocker Rocker/Camber/Rocker shapes seek to give you both hard-carving edgehold on firm snow from camber underfoot with enhanced turnability and float in powder from the rockered tip and tail. This profile is increasingly popular for freeride boards designed primarily for soft snow.

Flex Rating:
Medium

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.
