The Rainier 3-part Glove System Each glove layer is worn separately as conditions change during the climb.\r\nLight Weight Gloves \r\nA light pair of gloves are worn for much of the climb. They can be fleece, soft-shell, or a wind block/wind-stopper type material. Most of these will have a leather or synthetic palm for better gripping. Light gloves provide a bit of insulation and protection when holding the ice axe.\r\n\r\nMedium Weight Gloves Your medium weight glove is a typical ski glove, insulated but with dexterity. They are worn for most of the upper mountain climb. Guides generally prefer gloves with leather palms as they are more durable, wind proof, and can be waterproofed repeatedly. \r\n\r\nHeavy Weight Gloves or Mitts The heavy weight glove or mitt is worn high on the mountain in cold or stormy conditions. Even in the middle of summer, blizzard type conditions and high winds can force climbers to use this level of protection.\r\n
