Even when it’s fully packed, the MarsBro is easy to transport using either the dual carrying handles or the adjustable cushioned shoulder strap.

Users have found the polyester fabric to be quite durable and have been able to hold a considerable amount of weight. The zippers are also strong and hold up to normal tension, which is always a good sign since most inexpensive bags tend to scrimp on the zipper quality.
