G2 Evo is the ultra thermal double boot for extreme mountaineering and prolonged use at low temperatures. It provides maximum water repellency thanks to the internal thermo-taping and the innovative UltraSonic Welding technology which allows the materials to be joined together without the need for stitiching, the external anti-drag materials and to the internal insulating package of the shell. Resistance to abrasion is guaranteed by the use of Cordura®. The bootie is made using quick-drying materials to allow prolonged use in the mountains. Volumes and weight are extremely contained thanks to the Honeycomb Tech midsole in carbon fiber and to the compact, high-performance construction in traditional La Sportiva style. The inner shell adopts the Boa® Fit System quick-closing system in a double configuration that guarantees a fast, easy and precise fit and differentiated shell tension between the upper and lower part. The Boa® Fit System placed outside the gaiter allows the closure to be adjusted without having to open the zipper of the external gaiter, ensuring the maintenance of the internal temperature and the possibility of acting on the closure system without removing gloves. G2 Evo belongs to the La Sportiva high moutain line and is the ideal product for mountaineering use at heights ranging between 6000 and 7000 meters.
