Whether you’re going home for a weekend, traveling abroad for a month, or taking a road trip across the country, you’re going to need a pack that is functional and efficient. The Gregory Praxus 45L is that pack. It's great for traveling light and fast, and you can carry it as a suitcase or wear it as a backpack, depending on how big of a rush you’re in. It weighs just under 3.5 pounds, fitting in most overhead bins. Plus it has lockable zippers for extra security. My favorite feature: two compartments separate your dirty stuff from your clean stuff.
