The Patagonia Critical Mass 20L Pack is a backpack for bike couriers and commuters. Inside you’ll find a raised padded sleeve to protect your trusty laptop, up to 17 inches. You’ll also find organization pockets for smaller electronics, keys, wallet and your favorite pens. I like the gel kind. Plenty of space in the main compartment for your jacket and lunch. On the exterior you’ll find two water bottle pockets and thin daisy chains to strap a light or bike lock to. Sling the mesh straps over your shoulders and buckle in the lightly padded hipbelt and the shape and streamlined design keeps your load close to your back. Just what you need for better stability on the old two wheeler.
