The E-Jack Knife is the Pro model of Eric Jackson - a snowboarder who may look "seasoned" by age, but whose riding is anything but calm.

The model uses C3 - a profile with strongly dominant camber and a slight hint of rocker between the feet. That is enough not to lose the freedom of rocker completely, but the main character stays strong, direct and springy.

The board is directional, but the difference between nose and tail is not extreme. This allows nose tricks, transitions and natural freestyle even in serious terrain.

The E-Jack Knife is great for carving on the groomers, for deep snow, for chopped-up natural terrain and for big landings. The core is strong with a lot of pop, and the good sintered base (faster, holds wax) underlines its high-level character.

Technical highlights: directional C3; HP construction; sintered base; about 1" setback; flex around 6-7; freeride / carving / deep snow / freestyle in natural terrain.

Size is not chosen by length alone. Weight, surface area, waist width, profile and the effective edge (the part of the edge that cuts into the snow) together decide how a board rides. The table shows the minimum rider weight Mervin gives for each size. A shorter board turns faster and is more playful; a longer one brings more stability and float. The waist should fit the boot: at about 24-25 cm, boots are usually up to size 42-43 (EU), at 25-26 cm up to 44-45, and the W versions are for bigger feet, so toes and heel don't drag in the snow when carving.
