BD has evolved this technical, all-terrain tool with a new hydroformed shaft to increase stiffness & reduce weight, while maintaining exceptional clearance. Hydroforming uses pressurised water to expand the Vipers shaft into its uniquely stiff, yet lightweight shape. With superb balance, leashless capability & an optional integrated Android Leash, the Viper shines on icefalls or mixed ground. Comes equipped with Viper Fang & Strike, to cradle your hands for precise gripping when going leashless & the Laser Pick is fitted as standard.
