Lib Tech EJack Knife 2021 *PREORDER*

Size Chart
- +


Eric Jackson's Lib-Tech pro model board suits his history - he grew up riding the Mammoth park then transitioned to riding everything steep and deep he can find, and his board is designed to handle it all. With C3 camber and a medium stiff flex for loads of pop, edge hold and stability, riding away from giant landings and big drops aren't a problem. Added basalt absorbs vibrations from fast riding, and the lightweight tip and tail make getting those spins around easy. A serious board for serious riders!


This board is scheduled for delivery to Melbourne Snowboard Centre in June 2020. This is an estimated delivery window and is subject to change. You will be notified via email once your board is ready to be collected in store, or once it has been shipped (if being shipped).
