I use this regularly for air travel (3-4 trips a year). It easily holds a week of clothes and my toiletries. It's well built; zippers never snag, not rips or unravelled threads after two years, collapses into a flat package for storage. All in all, it's been perfect. Plenty of room for extra shoes and has a small front pocket that's perfect for cords, phone charger, and similar small want-it-quickly items.
