No matter where you’re off to, the new Knack Bags All-Purpose Backpacks will hold your belongings. Plus, these aren’t just professional backpacks—they’re also designed with a hidden expandable packing section for travel. This series of everyday backpacks come in small, medium, and large sizes depending on what you need. And the sizes aren’t arbitrary, as Knack Bags notes how much each travel bag can hold. The small size carries a couple of outfits and a 13-inch laptop, while the medium holds two to three outfits and a 15-inch computer. Furthermore, the large backpack has room for up to four changes of clothing and a 17-inch laptop. Available in four classic colors, these all-purpose bags blend right in with your style. Each size fits in airplane overhead bins, and they all fit underneath the seat in front of you as well. Be ready to jet off anytime when you unzip this expandable travel bag, revealing its second compartment.
