Osprey Kestrel Men's Outdoor Backpack, 38L, Bonsai Green, L/XL

Osprey Kestrel men’s 38L outdoor backpack in Bonsai Green

A 38L men’s outdoor backpack with an integrated raincover, trekking pole attachment and adjustable AirScape backpanel for stable, close-to-body carry.

The Osprey Kestrel is built for bigger days on the trail, with a 38L capacity, a close-to-body carry and practical details that help keep gear organised when the route gets more demanding. The Bonsai Green finish and L/XL size make this a clear fit-focused choice for men who want a pack that sits securely and feels stable on the move.

What the Kestrel is set up to do

This pack includes an integrated raincover, trekking pole attachment and easy-access organisation. The raincover stores in a zippered pocket at the base of the pack, so it is there when the weather turns without taking up extra space in the main body.

The AirScape backpanel is designed with updated adjustable torso lengths and a new injection-moulded framesheet. Osprey describes this as giving a stable, breathable, close-to-body carry, which is especially relevant when the trail becomes more technical.

Materials and fit details

The pack uses bluesign approved fabrics and DWR treatments made without PFAS. Osprey also notes that the Kestrel/Kyte fit is body-specific for comfort and stability, with men’s packs intended for body types different from the women’s range.
