The inner shell uses our patented CORE-WRAP™ System that combines heat-insulating fabric with structural reinforcements, so you can expect superior performance, much-needed warmth, and stability. The Vibram® Olympus tread is super lightweight to reduce fatigue on long expeditions. The BOA® Fit System offers a precise fit. Plus, you can quickly tighten or loosen the boots without removing your gloves. Ready for changing conditions? The gaiter is made from ultra-lightweight, durable, water-repellent monolayer fabric with internal heat-welded seams for reliable weather protection. The removable liner also includes a layer of Primaloft® Gold Insulation Aerogel for effective underfoot insulation when conquering the most intense terrain.
