Minimalist Precision for Fast-Paced Rides

The Osprey Raptor 4 is the most compact and aerodynamic pack in the Raptor series, designed specifically for mountain bikers who want to stay hydrated without the bulk of a traditional pack. This minimalist powerhouse is built around an included 2.5-liter Hydraulics™ Reservoir, ensuring you have ample water for high-intensity trail sessions or race-day efforts. The Winged Harness design is a standout feature, wrapping the torso to provide a "cradle" fit that eliminates shifting and bouncing during technical descents or aggressive out-of-the-saddle climbing.

Despite its slim profile, the Raptor 4 doesn't compromise on technical features. It utilizes the LidLock™ helmet attachment, allowing you to quickly secure your helmet when you're off the bike. The main compartment is intelligently designed to hold a spare tube, CO2, and a multi-tool, while the AirScape™ backpanel ensures maximum ventilation and keeps the load weight perfectly centered. Constructed with bluesign® approved recycled nylon and featuring a PFC-free DWR finish, the Raptor 4 is a durable, eco-conscious tool for riders who prioritize speed and efficiency above all else.
