Know that feeling when it starts to get cold, you reach into your pack to pull out a puffy, and then you remember you left it at home because it didn't fit' No fun. Gregory's Baltoro 75 Backpack has over 4,500 cubic inches of gear toting capacity to fit all the puffies, fleeces, and longjohns you need, so you can be seriously prepared on weekend backpacking trips or pack more efficiently for three or four day excursions. Both the pre curved Auto Cant harness and EVA foam Auto Fit hip belt pivot independently to conform to your body and keep you balanced on tough terrain, and the single aluminum stay provides lightweight structure and helps distribute weight evenly across your back, hips, and shoulders. The Baltoro's fit and carry are what set it apart, but it's also optimized to hold two, three, or four days' worth of backpacking gear and adapt to the demands of your trip. The removable lid has two pockets and doubles as a lumbar pack if you're going on short basecamp explorations or summit hikes, and the pockets on the front, side, and hip belt keep layers, snacks, maps, and other essentials where you can reach them. Gregory also built in a hideaway water bottle pocket on the side of the pack and included a hydration compatible sleeve with multiple easy to feed hose ports. A series of lash points, loops, and compression straps hold everything from trekking poles to ice axes to that sweet stick you just found, and the DWR coated water resistant zippers and reinforced bottom help stop rocks and rain from putting some serious cramps in your backcountry style.
