What Our Gearhead(R) Experts Are Saying: "The Phantom Tech HD is my go-to boot for technical ice-warm, dry, and shockingly light. The HDry liner and integrated gaiter keep my feet bone dry even after hours on vertical ice, and the Fast Lock lacing gets that snug, secure fit you need for delicate placements." For alpine athletes chasing vertical ice and mixed terrain, the Scarpa Phantom Tech HD Mountaineering Boot stands at the cutting edge of lightweight performance. Every detail-from the integrated gaiter to the carbon-reinforced sole-has been fine-tuned for maximum warmth, precision, and protection in punishing alpine conditions. The waterproof Schoeller(R) Ecorepel Bio gaiter and HDry(R) laminate create an impenetrable barrier against snow and meltwater, while PrimaLoft(R) Gold insulation ensures warmth without weight. Inside, Scarpa's Sock-Fit XT construction and Fast Lock closure wrap the foot securely, eliminating bulk for exceptional sensitivity and stability on vertical ice. Underfoot, the Vibram(R) Precision Tech Roll sole with Durastep rubber grips confidently across rock, snow, and glassy ice. We love that Scarpa managed to pack this level of warmth, support, and waterproofing into a boot that weighs just 800 grams per pair-a true testament to Italian craftsmanship and modern alpine innovation.
