This lightweight hiking backpack is now even lighter and features the Aircomfort back system for maximum ventilation. With VariQuick back length adjustment, an adjustable chest strap, ergonomic shoulder straps, and hip fins, this no-frills backpack provides the comfort you need for long hikes or treks. As a top loader, the contents are easy to pack and unpack. A phone or snacks can be quickly accessed in the airy stretch-mesh side pockets. A helmet holder can be attached to the front using special attachment loops.
