The new PHANTOM is now lighter - thanks to Vibrams Jorasses Gsb mid and out soles. This technical high altitude triple boot is ready to tackle any route in any region of any range. Fitted with the (Grivel System Binding) with positive tongue-in-slot front connection your PHANTOMS will maintain the lowest profile with use of either the Grivel AIRTECH or G14 GSB crampons - with total security. Of course any crampon with toe basket and heel cam may be used with good effect. From the inside out the PHANTOM is about warmth and fit. IS Thermo-Fit (heat moldable) Liner affords a custom fit - for greater foot comfort and retention. Nice! The structural middle boot is comprised of aluminum faced, heat reflective foam panels, loden lined and speed laced also - to give you the best possible foot retention and gloved hand convenience. Streamlined gaiter has T-Zipper, breathable upper with cut resistant Cordura-Keprotec lower section backed by a layer of closed cell foam for total weatherproofing and additional warmth.
