Speed Lock system Lite
Speed Lock system Lite New

Lacing system, consisting of the lever “A-Light”, lightweight and durable, a Dyneema cord, two loops and two metal hooks. Thanks to this system, the cuff and the shell can be released or locked in a single movement, allowing the front opening or closing of the cuff. The new locking plate on the shell, for the connection of the lever to the shell, assures a secure and fast locking and avoids the heap of snow or ice.
