This is my second Pacsafe product. I have a smaller travel bag that kinda looks like a purse. The Gii 350 is very durable, and just from looking and feeling this pack you know that it was designed with security in mind. This product is also lightweight which is really nice since most people may be using it when traveling. The size is a tad bit smaller than your standard backpack that you may find at your local retail store, but I think it's a perfect size to carry a good amount of belonging while walking though a city or hiking. You can easily fit a laptop, DSLR camera, Mini tripod etc... I highly recommend this backpack because of it's size, weight, looks and comfort. Also you just can't go wrong with the Pacsafe brand.
