The Black Hole Wheeled Duffel 40L is a burly, legal airline carry-on duffel. Tough and highly weather-resistant, this durable bag protects your gear from the scuffs and scrapes of wayward journeys. Its zippered U-shaped lid - with two zippered internal mesh pockets on the underside to keep small items organized - offers quick and easy access to the main compartment. A zippered exterior pocket provides a secure and handy spot for your boarding pass, energy bar or paperback. The sturdy frame sheet protects the duffel from baggage-handler abuse and keeps your Black Hole upright, even when it s loaded to the max. Oversized wheels deliver a smooth ride, whether you re crossing the tarmac or traversing a cobblestone street. Carrying options include the main webbing handles (with snap closure), a two-position telescoping handle and the two haul loops on either end. You can lash additional gear to the outside with the four corner-mounted daisy chains. Made from 900-denier 100% postconsumer recycled polyester ripstop with a TPU-film laminate and lined with 200-denier 100% recycled polyester with a polyurethane coating. Both fabrics have a DWR (durable water repellent) finish.
