The Aquasack is an ultralight insulated bottle holder that does a great job of helping to keep your water from freezing in cold conditions. It also keeps a drink nicely chilled in hot weather. The Aquasack does this by wrapping a 32 oz. Nalgene (or bottle of similar size) with a unique "double bubble" insulating layer sandwiched between two heat-reflecting foil layers. The insulated lid closes with a draw cord (no fighting with frozen zippers). You can keep your bottle handy by sliding your pack's side compression straps or hip belt through hook and loop straps on the Aquasack. The outer shell and liner are constructed of tough, 210-denier packcloth. |
