In my never ending quest for the perfect day pack, I’ve finally put one to the test. We purchased these specifically for our latest trip to Europe where we were only allowed 11 lbs. each for our carry on bags on trans-atlantic flights on WOW Air. I was initially skeptical that it would hold up to three weeks of fully packed traveling but I must say that I was pleasantly surprised.
For ~$15, it’s worth having one per person. They weigh 0.56 lbs. and fold up into the front pocket for easy storage.
