A nice product when you need to have a day pack. Folds up nicely in pocket. Though you can't really carry heavy items, it works to keep your stuff contained while traveling. The pack could be improved with additional pockets inside.

I usually travel with only carry-on and have a bag that goes in the overhead and a larger backpack that goes under the seat. Don't really fancy carrying on my larger backpack during my day touring. Hence this backpack works great for the day.
