REI offers its REI Traverse 30 Pack in Black for $61.93 with free shipping. That's $28 off and the lowest total price we could find, although we saw it for $6 less two weeks ago. It features a water bottle pocket, TipGrip loops, and spring steel perimeter frame that transfers weight to a padded hipbelt.
If you're at least 62 years old, you can score a $10 lifetime pass to America's federal parks and recreational lands. But act quickly because fees are about to jump.
