Osprey Kestrel Men’s Backpack 38L, Bonsai Green, S/M

Osprey Kestrel 38L men’s backpack in Bonsai Green

A 38L hiking backpack with an integrated raincover, trekking pole attachment and adjustable AirScape carry system.

Built for longer days on the trail, the Osprey Kestrel 38L is a men’s hiking backpack with a practical 38-litre capacity and a close-to-body carry. The Bonsai Green finish gives it a clean outdoor look, while the S/M fit is designed to suit the smaller end of the men’s sizing range.

The pack is aimed at days when you want organisation, weather protection and a stable carry without overcomplicating things. It includes an integrated raincover, trekking pole attachment and easy-access organisation, so the essentials are close to hand when you need them.

Carry system and fit

The AirScape backpanel is designed for a breathable, stable feel against the back. Osprey also notes updated adjustable torso lengths and a new injection-moulded framesheet, which are intended to improve comfort and stability on more technical trails.

Kestrel and Kyte packs are shaped around body-specific fit, and Osprey states that men’s packs are best suited to body types that differ from the women’s range.

Materials and weather protection

The pack uses bluesign approved fabrics and DWR treatments made without PFAS. The integrated raincover stores in a zippered pocket at the base of the pack, so it is ready when the weather turns.
