La Sportiva G-summit Liner

"The G-Summit liner from La Sportiva is the ideal addition for the most extreme weather conditions and demanding mountain adventures. By inserting the special liner into the shell, insulation is significantly improved, making the G-Summit the lightest choice for expeditions in high altitudes and extreme environments. This configuration is perfect for mountaineers and high-altitude trekkers who value warmth and insulation."
"When using the liner, the Thermoinsole is removed to ensure optimum fit and maximum compatibility. For technical mountaineering activities where lightness and precision are paramount, the G-Summit can be used without a liner and with a Thermoinsole. This setting offers maximum performance even in the most demanding and tricky passages"
"The G-Summit Liner is an essential accessory for anyone who specializes in ice climbing, mixed climbing and glacier activities at medium to high altitudes. Its unisex design makes it the perfect choice for all genders looking for adventure in the mountains."
