The Kestrel is a hiking backpack ideal for outdoor travelers and professionals who love exploring new places with a backpack on their back. Thanks to the volume , you can pack everything you need for a multi-day high mountain expedition as well as several weeks of backpacking in Southeast Asia. The main compartment is accessed not only through the top, but also through a U-shaped zipper around the perimeter of the front panel, which makes it easier to organize things and equipment and find what you need. The backpack offers plenty of storage space inside and out - for example, an adjustable canopy with an inner and outer pocket, a stretch front pocket, mesh side pockets or pockets on the waist belt. There are also straps for attaching trekking poles or ice axes and loops for attaching material and equipment. The backpack is made of strong, sustainable materials (nylon) that can handle rough handling and is treated with a water-repellent DWR treatment (made without the use of PFAS.). The AirScape back panel offers improved torso length adjustment and a new injection molded frame, ensuring stability, breathability and a great fit for comfortable wear even on challenging trails. Integrated raincoat stored in a zipped pocket at the bottom of the backpack. Canopy (adjustable) with large zipped pocket and lower mesh zipped pocket with carabiner for keys. Ability to attach equipment and material to the top panel. Inner pocket for a water bag with a Hydraclip clip for easier hanging of water bags. Stretch front pocket. Two "daisy chain" straps with eyelets for attaching equipment to the front panel. Two lateral compression straps in the upper part with the option of fixing an ice ax/trek poles. Two lateral compression straps in the lower part.. Detachable straps for the mat. Zippered sleeping bag compartment with movable partition. Two ice ax loops. Stow-on-the-Go system for attaching trekking poles. Two mesh side pockets. Access to the main compartment from the top and with a U-shaped zip around the perimeter of the front panel. Detachable top pocket. Internal compression strap. The 3.5mm LightWire perimeter frame effectively transfers the load from the straps to the waist belt. Fit-on-the-Fly™ waist belt with pockets. The Atilon frame distributes the load across the entire back panel into the perimeter frame. Mesh-covered foam lugs allow for maximum ventilation while ensuring that the load is snug against the body. Fine padded mesh offers a soft and breathable contact surface and great support under load. Adjustable chest strap with emergency whistle.
