This Transporter Bag, is an excellent bag for my purposes. It is strong but also light. So far it seems to be waterproof. It is professional looking, so can be used for business. At the same time it provides plenty of expansion space so that I can use it as my overnight bag as well as laptop bag when travelling on business. It is also comfortable to use as a backpack when I want to walk between offices, rather than take a taxi. Truly a multi-functional bag that will stand up well to everything I require of it. And all at a very fair price. Ordering and delivery went very well. Thank you.
