ALPS Mountaineering Red Tail Backpack - 4900cu in - $125.96

When a day, a weekend, or even a week isn't enough time on the trail, load up the extendable 80-liter ALPS Mountaineering Red Tail Backpack and remove yourself from civilization until you fill the void with a adult-sized dose of wilderness. Not for mere weekend getaways, this six-pound pack outfits the month-long treks you plan for weeks and then quit your job to complete start to finish. The top spindrift collar extends to provide more than 80 liters of space, but since its dual-density shoulder harness adjusts to fit your exact torso size you can be sure that all that weight doesn't crumple you in the first five miles. - $125.96
