Krista Hallwrote a review of Osprey Packs Raptor 10 Hydration Pack - 488-610cu in on September 13, 2012
Familiarity: I've put it through the wringer
Water- check. Carbs- check. Rain gear- check. Let's Go! Here atop Hahn's Peak with Steamboat Lake in the background.
My only complaint- it is Not comfortable when I do long rides on my mtn bike when I need more than two water bottles. I've adjusted and readjusted and it still presses on my spine. Good upright though.
