The Expedition Trail Pack series features extremely durable material used throughout the bag. It includes a top lid for extra storage. Despite being a large volume pack, this model provides stability and balance to the pack when it is shouldered. Eliminating seam lines improve durability and reduce weight. This multi-day expedition pack can be used for trips abroad and an optional water resistant inner sack can be used to increase the pack's weatherproofing.
