Why We Like The Osprey Kestrel 58L Backpack

Osprey's Kestral line was built to excel in rough environments, and the Kestrel 58L Backpack is the ideal size for multi-day adventures and trips that require the whole gear closet. Ultra-durable earth-friendly fabrics withstand encounters with sandstone and alpine brush, and an included rain cover offers additional defense when the weather turns. Osprey's AirScape technology offers a stable, close-to-body carry that allows airflow for cool, wicking comfort.

Hefty trips call for loads of gear, and the Kestrel 58L Backpack kept that in mind. Daisy chains, quick-release trekking pole loops, and compression straps keep our trail equipment secure while our packs are full with our camp necessities. An internal reservoir sleeve with Hydraclip keeps water accessible.
