The Osprey Kestrel LT is a versatile 45 L hiking backpack that can handle day hikes, multi-day treks and travel. It combines durability, comfortable carry and a simpler yet practical feature set.
The construction uses technology from the Talon™/Tempest™ frame, thanks to which the pack fits the body precisely even in more demanding terrain. Durable recycled polyester ensures a long service life and low weight. It is suitable for versatile outdoor enthusiasts who want one backpack for different activities and conditions.
- Stable and comfortable carry
An injection-moulded framesheet and 4 mm LightWire™ frame transfer the load from the shoulders to the hips, while the AirScape back panel with mesh-covered foam ridges and soft straps with breathable spacer mesh ensure good ventilation and comfort. - Practical access to your kit
The main compartment can be loaded from the top or via a long side zip, and triple-slider zips on the front and side let you reach items from anywhere, so you don’t have to unpack everything.
