Details La Sportiva G2 Evo Mountaineering Boot The La Sportiva G2 Evo is an exceptionally light and warm mountaineering double boot, aimed at 6-7000m peaks and winter alpine climbing. It provides maximum water repellency thanks to the internal thermo-taping and innovative UltraSonic Welding technology which allows the materials to be joined together without the need for stitching. Resistance to abrasion is guaranteed by the use of Cordura®. The inner bootie is made using quick-drying materials to allow prolonged use in the mountains. The Boa® Fit System placed outside the gaiter allows the closure to be adjusted without having to open the zipper of the external gaiter and is easy to use even with thick gloves on. The G2 SM doesn't come with an insole - so you can add your own to customise the fit.
