Make the most of every ride with Osprey's Raptor 10 pack. It's made from rip-stop nylon and contains plenty of pockets, including 1 for the 3 liter reservoir, 2 quick-access front pockets, and a main compartment with a tool organizer. There is a rigid AirScape back panel that keeps you cool and won't deform when fully loaded. So, no matter how how crazy the trail gets the Raptor won't overheat you and it stays in place! What's more, the Raptor boasts compression straps, a helmet attachment, a hip belt with pockets and a supportive harness system for comfort that lasts all ride long.
