Options are the name of the game and the Gregory Baltoro 65 delivers just that. This pack is the answer for those of us who don't need to pack the kitchen sink on a weekend backpacking trip. With all of the same targeted features and functionality as its bigger brother, and updates to the award-winning Response AFS suspension, you'll be more comfortable, go farther, and be the envy of everyone else on the trail. Torso Range- Small:16-18 in., Medium:18-20 in. Large:20-22 in.
