I think the best this about this is that it can be used in multiple ways. It is small enough to carry the essentials without being weighted down.
It doesn't' come with a strap but if you would like to have one on it let me know. With a strap it makes a great over the shoulder bag. The front flap attaches with velcro.
It is made from a soft green material with a contrasting green and yellow lining on the inside. It is lined with fusible fleece to reinforce it and provide greater protection.
