An essential 30-liter-volume backpack features a spacious main compartment with a padded tablet sleeve and a separate padded laptop pocket. Toggled elastic straps are perfect for stuffing a warm layer while hiking, or strapping down whatever won't fit inside. The built-tough plain-weave nylon construction with a DWR coating will not only protect your goods, but keep them dry as well, while heat-venting airflow mesh back and straps keep you cool and comfortable on those long excursions.
