This lightweight backpack was great to have during my 5-week to Japan

This super-lightweight backpack came in very handy during my 5-week working holiday in Japan. It has two pockets for water bottles, which was useful because temperatures approached 100 degrees almost every day. There are two other front pockets for battery packs, pocket wifi, sunscreen, sunglasses, notepad, and other small items. The main storage area is for hats, more water, laptop, guidebooks, and items bought while shopping. It folds up to a tiny size. I'm really happy with it. It's $21 on Amazon.
