For quick jaunts around town, short flights, and Sunday dayhikes, a compact backpack is absolutely essential. This one from Topo Designs fits the bill with rugged, ballistic Cordura nylon and tons of upgraded details. We're talking sturdy top-carry handles, heavy-duty YKK zippers, Packfast clips to secure it to a rolling suitcase, and more. TLDR: it's a really good backpack.
