Mountainsmith Insulated Bottle Holster

There's nothing worse than craving a cool drink and getting a mouthful of tepid water instead. That's why you keep your water bottle in the Mountainsmith Insulated Bottle Holster. A hook and loop strap lets you attach this holster to the waistbelt of your pack so that your water is always close at hand. Foam insulation protects your water from extreme temperatures, whether you're in the middle of a summer trek or snowshoeing into a yurt for the weekend.
