Combining strength and lightness, the black Pelican 1615Air Wheeled Check-In Case with Pick-N-Pluck Foam is watertight, crushproof, dustproof, and optimized for travel. For travel by air, Pelican has aggregated available airline rules for check-in dimensions with the goal of creating a case that conforms to their requirements. Of course there will always be exceptions, so it’s wise to contact your carrier before departing.
