The Billabong Alpha Travel bag has been designed specifically as a carry-on cabin bag, and sized to fit in an overhead airline locker. Constructed from a durable polyester 300D ripstop with a clamshell design, a telescopic tow-handle and skate quality wheels. Great for a long weekend away when you want to avoid the whole baggage collection ordeal and ideal to use in conjunction with one of the larger luggage pieces.
