Jack Wolfskin's EDS Dynamic Pro Backpack offers a comfy carry and convenient organization for overnight trips. Its Ergo Dynamic System is a well ventilated suspension with a dynamic design for freedom of movement. The Ergo Dynamic System also features a spring steel frame for relief and support. Abrasion and tear resistant Chaintech works with the lightweight Crossrip to make the EDS Dynamic Pro durable for the outdoors and comfortable while hiking. What separates the EDS Dynamic Pro Backpack from most overnighters is the vertically divided main compartment. This feature includes a waterproof inner section for your hydration reservoir, a larger inner section with a secure roll top access, and another quick access section via the front zipper. There are more pockets in front, up top, and at the sides for personal organization. Lashing points secure trekking poles, and side compression straps ensure a secure load.
