OSPREY KESTREL 38 is a durable trekking backpack with a volume of 38 liters for multi-day hikes, via ferratas and lighter expedition trekking. Weighing around 1.7 kg it offers a robust construction, ventilated AirScape™ back system and integrated attachments for a full range of outdoor equipment. A key advantage is the adjustable torso for a precise fit and a top lid with access to the main compartment from above and the side.

Ventilated AirScape™ back system and adjustable torso

The AirScape™ back panel made of molded foam with deep ventilation channels covered by mesh ensures breathability on long hikes. The adjustable torso (sliding yoke) allows adaptation of the back support length for different body types – the pack fits both smaller and taller people. The stiff frame distributes load weight to the hipbelt and relieves the shoulders even with 15+ kg of gear.

Generous organization and integrated raincover

KESTREL 38 offers dual access to the main compartment (top and side zipper), a separate sleeping bag compartment, two stretch side pockets, a large front pocket for wet gear and two zip pockets on the hipbelt. Hidden at the bottom is the integrated raincover that protects the pack during a sudden storm. Stow-on-the-Go™ trekking pole attachments, an ice tool attachment and stretch compression straps complement its versatility.
