Tumi Voyageur Weekender 

"I haven't had a chance to actually use this bag yet. But, the size is very large and it will definitely suffice for using as a carry on for my laptop, toiletries, extra set of clothing, etc. There are no dividers inside - just a large open space. I could see how this might make it hard to find things in such a big bag. Maybe a divider in the middle would have been nice. The straps seems slim for such a big bag...I am hoping the Tumi brand comes through and that the slim straps are super durable. The bag is nylon, but still looks nice. It has the slot in the back so I can easily attach it to the handle of my roller bag - very important feature!! Pockets on the outside make it handy for travel documents such as boarding passes and passport, etc. I think this bag will work well, I just hope it's durable and holds up to heavy duty travel."
