If you asked the endurance racing crowd or if you surveyed the bikepacking group, the folks that spend hours and days crossing remote sections of the countryside, as to what backpack/hydration pack was a favorite among them, the Osprey Talon 22 would be at the top of the list. It is lauded for its comfort, design, and construction. In the world of hiking, multi-sport and mountaineering, Osprey is well known. It turns out that Osprey has been making packs for some time now and in 2009, celebrated 35 years in the business.
Now, in addition to more types of packs than you can imagine, they have added a new line of hydration packs under the Hydraulic banner. Called the Raptor series, they are pointed directly at mountain bikers although they could apply to a multi-sport application.
