If you like to travel light, Outlier's new Ultrahigh Duffle may be your new favorite piece of luggage. Made from a strong and waterproof ultra high molecular weight polyethylene from Dyeema, the material is lightweight and abrasion resistant.
And while it can pack a whole lot, the bag really shines when you're packing just the essentials. The rolltop design allows it to shrink to the size you need and expands when you need to pack a large haul. It also has a versatile carrying system that lets you throw it over the shoulder or wear it as a backpack with the additional strap.
