I’ll be the first to admit having a bag problem. Over the course of a season of mountain biking, I’ll cycle through an embarrassing number of bags in search of the perfect combination of fit, capacity, and features. Though I do have a handful of standbys that I rely heavily on, when word of Osprey’s first mountain bike specific range of packs began popping up last fall, I had to have a look. The Raptor range (6, 10, 14 and 18) has a whole bunch of shared features that makes the bags stand out from the large number of ‘me too’ hydration packs on the market. Excited by the Raptors’ potential and positive early reviews, I managed to get my hands on a Raptor 18 for review.
