The RationRack™ is a strong, lightweight, easily repairable alternative to single use 1 quart plastic freezer bags. Weighing in at 4.5 grams it is even lighter than its plastic alternative. The unique, yet classic roll top closure system, and use of Dyneema Composite Fabric® provide excellent water resistance. With a one liter capacity, the RationRack™ provides plenty of space for all your dry goods, while still allowing enough rolls to perform its function as a dry bag. AND it is easy secure with a lightly tightened square knot! Easily organize and label each individual bag with permanent marker and any common sticky label (9 labes included). The unique and ultra minimalist tie top closure system increases durability and reduces weight compared to plastic buckles commonly used by competitors in similar dry bag construction.
