Why look like an overpacked thru-hiker when you're just out for the day? Many so-called day packs have so much room and so many pockets, you could pack enough gear in them for a week in the woods. For a lighter, truly minimal pack that has all you need for a day's outing, there's the Topo Designs Trail Pack. 

Made from 500-denier Cordura, the 15-liter cinch-top Topo Designs Trail Pack features a deep interior pocket, comfortable straps, and four paracord loops for exterior storage. It's durable, stylish, and stripped of every nonessential detail. It's also awesomely inexpensive, coming in under $100.
