The 2021 Burton Lexa X EST Binding is a new addition to Burton's lineup. Compared to the original Lexa, the Lexa X provides a lightweigh binding with more performance by creating a stiffer flex for greater response. This binding is designed for the rider who wants to push the envelope and charge the mountain. A great option for ladies who ride boardercross or race downhill and is after a step-up to the traditional Lexa binding. Double Take Buckles allow the Lexa X to easily ratchet while the asym hammockstrap and supergrip capstrap will have you locked in and comfortable from the first lift till last.This is the EST version and is only compatible with the Burton channel system, creating a more natural feel and flex, allowing the board to ride as it was designed.
