I recently got the opportunity to acquire a handy travel accessory that I would not have purchased under normal circumstances- compression packing cubes. These packing cubes were advertised to increase packing efficiency and available space in your luggage, and naturally I was a bit suspect.
The product always seemed like a bit of a wash to me, as it sounds somewhat unreasonable that a zippered packing cube best organizes my luggage and saves space. And prior to receiving them, they were not something that I would ever want to spend $20 per set for.
But after receiving them I have to say, I was impressed. Now I never leave home without them.
