The Genius Pack may seem like a hyperbolic title, but this bag is smarter than you think. The fourth-generation Genius Pack features a polyurethane coated fabric, patented Laundry Compression Technology (which helps compress your clothing up to 50%), and an expandable footprint. It has an integrated air valve to help free up extra space in your bag and compartments for literally everything you want to bring, plus a checklist to make sure you have all the things that fit into those compartments. The Genius Pack even comes with a built-in umbrella, so you don't have to worry about getting caught in the rain on your way to your hotel and a hook for your jacket.
