It comes with a toiletry bag and an adjustable and detachable sling strap. 

20” x 7.9” x 13.8”, large enough for your carry-on essentials but not too bulky to fit under the seat in an airplane to avoid paying extra and keep personal items safe. It is made with sturdy canvas fabric, sporty style, a durable carry-on size crossbody individual items travel bag that is lightweight for a weekend trip or a gym visit.

You can easily fit 3- 5 days' clothes and toiletry bag or baby supplies in the main compartment, wallet and important documents in the large zipper pocket inside, and six outer quick access pockets for your hats, water bottles, umbrella, books, and anything else! 

The luggage sleeve on the backside makes it easy to attach to the handle of roll-around luggage; the convertible, adjustable long strap can be folded nicely to pack away when not in use.
