Lib-Tech EJack Knife 2019

Size Chart
- +


The 2019 E Jack Knife is the pro model of Eric Jackson, a rider known for aggressive big mountain freestyle snowboarding. Serious lines require a serious board, and Eric has tuned this one to handle whatever the snow can throw at him, from hard carves and deep powder to the occasional park lap, but high speeds and aggressive riding is where this board thrives. Think of it like a Ferrari, you want to get it out in the open and let it run wild, not have it cruise through the suburbs on a leisurely drive. Lib-Tech have delivered a powerhouse of a snowboard, with a super light Horsepower construction, aggressive C3 camber, and a mild tapered shape for effortless float, making the EJack Knife the obvious choice for a powerful rider who needs their board to have a bit of fight.
