The Hydraulic Pro Dry Pack from Sea to Summit is a robust, durable, and waterproof duffel-style pack that can also be worn as a backpack. The removable Hydraulic carrying system is made of EVA foam covered with Airmesh fabric and is adjustable in length. It is secured to the Dry Pack with aluminum buckles. The seams are welded together, ensuring that no water can penetrate from the outside. The outer material is made from PVC-free, sturdy Hydraulic fabric, which is coated with polyurethane on both sides. This makes the fabric waterproof, abrasion-resistant, and pressure-resistant. Additionally, it is UV-stabilized and remains break-resistant even in extreme cold, ensuring long-lasting enjoyment of the Dry Pack. The oval base prevents the pack from rolling over when standing and makes it easier to store, stack, or pack. Whether for canyoning, expeditions, or boating: the Hydraulic Pro Dry Pack is ready for all your adventures!.
