The Patagonia 20L Atom Tote Bag is a small-size pack for everyday hauling of electronics that isn't afraid of travel or a quick hike. With a 20-liter volume, it includes a removable padded sleeve that fits laptops up to 13 inches and has a secure zippered pocket for pens, cords, and small essentials. A hydration hanger, pass-through access, and breathable back panel make it equally suited for trail adventures and daily commutes. The front stash pocket keeps small items within easy reach, and a bike-light clipping point at the base adds convenience for dark early mornings or late evenings.
