Query: Perfect!

This is exactly what I need. I'm going to Italy in a few days and I wanted to bring along a water bottle, but all I have are those big clunky Nalgenes, and I didn't want to carry something that bulky. This water bottle is perfect! I can roll it up and put it in my little purse and it fits great. It's not too hard to hold when you fill it up with water. This item is very portable and perfect for my needs.
