I am an Irish man living in Denmark. I bought this beauty on my first trip to New York. I've always had a backpack where I keep things, I like to travel and have emergency supplies of all sorts planted everywhere. This is a great size for a bag, wallet, keys, phone, notepad, personal organiser, Ipod, sunglasses, it all fits, and to each it's own section. I find it wonderul in the summer where you don't have a coat to keep all these things in and dont want to walk around with huge "rob me" bulging pockets. I was delighted to find this website too as my dog ate the strap on my first bag (now a good 5 years old), so looks like time for a new one!
