Hyperlite Mountain Gear Insulator

Hyperlite Mountain Gear's Insulator is built for winter backpacking, when your water bottle needs help staying above freezing rather than below it. Fill a wide-mouth Nalgene with heated liquid before you set off, slot it into the Insulator, and Thinsulate™ insulation slows the heat loss through the coldest stretches of the day. The shell is built from Dyneema® Composite Fabrics for genuine durability without adding weight, and a secure Velcro strap attaches directly to your pack's hip belt for quick access on the move. A mitten-compatible grab handle on the back means you can pull it free without taking your gloves off. Features Keeps liquids from freezing in cold conditions. Fits a wide-mouth Nalgene bottle, filled with heated liquid before heading out. Thinsulate insulation and Dyneema Composite Fabric shell keep weight down without sacrificing warmth retention. Secure Velcro strap attaches directly to a pack's hip belt for quick access. Mitten-compatible grab handle allows use with gloves on. Ideal for alpine or snowy expeditions.
