The new AC Lite, which also comes in a women-specific version (SL), is the ideal companion for day hikes. Their popular hiking pack is now even lighter and features their Aircomfort back system for maximum ventilation. A large zipper opening down the full length of the front provides an excellent overview of contents. A cell phone, snacks etc. are easy to access in the stretch mesh side pockets. And a helmet holder can be attached using dedicated docking loops on the front.
