If you're on the go and don't want to be burdened with a lot of gear or a bulky bag, take advantage of this 5L Everyday Sling in ash from Peak Design. Well-organized yet compact, this bag can hold a full-size DSLR camera with an extra lens, or a mirrorless body with up to two lenses. In addition to your core photo gear, an internal padded sleeve will hold a tablet and two small inner side pockets are great for batteries. The inside of the main flap offers yet more space, with several slip pockets where you can store cords, memory cards, and pens. Finally, a zippered external slip pocket allows for quick access to everyday items like your smartphone, wallet, and keys.
