Description

Osprey Berm Biking Hydration Backpack

The Osprey Berm is a streamlined bike hydration backpack designed for riders who want to carry water and the essentials without extra bulk. It includes a 2.5L Hydraulics LS reservoir with magnetic bite valve attachment, and its breathable AirScape backpanel keeps you cool on climbs. This pack is ideal for mountain biking, commuting, or any ride where you need hydration and a few small items.

Hydration and Convenience

The reservoir is easy to fill thanks to the S-zip access, and the magnetic bite valve secures to the sternum strap, so you can drink hands-free. The pack also features a zip pocket with a key clip for valuables, and reflective details plus a blinker light attachment (light not included) enhance visibility on the road.

Comfort and Stability

The bike-specific harness is designed for a riding position, keeping the load stable and close to your body. The mesh-covered ridged foam AirScape backpanel provides cushioning and ventilation, so you stay comfortable even on hot days. At just 0.97 lb, you'll barely notice it's there.

What Fits Inside the Osprey Berm 4?

The main compartment is compact but fits a spare tube, tire levers, a compact pump, a phone, a wallet, and a light jacket. The front zip pocket holds small tools or snacks. If you need more cargo capacity, consider the Berm 6 or 9 models.
