When traveling you always need a carry on that can fit a lot of useful products and clothes. I have used a lot of backpacks and I have found them to be great at certain things but really not so good on other issues. One of the main ones is digging around to find what you are looking for! So I recommend this backpack because you open it like a suitcase! First time seeing this it was literally eye opening! Also other good pointers about this bag is that you can expand it or decrease the size with these cool traps!
Until next time happy travels!
