I recently started using an Osprey Raptor 10 pack and let me say I like it. I picked up a Osprey Flap Jack pack for my work travel and really liked it. I was so impressed with the quality of the Flap Jack that I looked for a new hydration pack for 1 to 2 hour rides from Osprey. I got an Osprey Raptor 10 and it is a great bag.
This is quite simply the perfect day-to-day pack for hitting the trails. At 10 liters, it’s compact enough for a quick spin on the neighborhood trails yet roomy enough for a full-day adventure. Big Plus: The lid latch carrier makes it easy to attach your helmet to the pack with no bouncing around.
Osprey has just introduced two new hydration packs, the Raptor (above) and the Manta. The Raptor is the smaller of the two and is available in four sizes. It was designed specifically with mountain biking in mind and features dedicated tool, pump and other pockets inside the main compartment.
