Built for the two-wheeled commute, the Patagonia Critical Mass Bag is a large messenger bag designed to carry it all. The Critical Mass's main compartment is padded on the back and along the contoured base to provide protection and structure for the stay-open design. Inside, a removable, padded computer sleeve suspends a 17-inch or smaller laptop off the ground and has a file organizer built into its side. The cover flap extends over the sides of the bag to protect contents from rain and a low-profile front pocket closes with a water-resistant zipper. External side pockets hold a cell phone, keys and power brick. Other features include a padded, adjustable shoulder strap with a self-closing buckle, a removable shoulder strap pocket for easy access to an MP3 player or cell phone, a stowable waist strap, bottom compression straps that hold a yoga mat, and a reflective strip for better visibility in low light. Made with a 600-denier recycled polyester exterior and a 200-denier polyester liner; both have a polyurethane coating and a DWR (durable water repellent) finish.
Great Bag!
I use this for law school, and it will carry 4 full size legal texts as well as computer, papers, etc... It carries everything I need in a day, and that's saying something.

if I had to carry a kitchen sink, no problem
wow- what a bag. I regularly bicycle to work and this time of the year its cold in the morn and sort of mild in the afternoons- so every thing I wear on my morning ride goes right in along with every day stuff you drag around. Adjust the strap so it sits high on ya back and cinch the cross over strap tight and you don't even know your carrying anything on your back- LOVE IT

I do NOT go for the "salesperson type approach" this is why I choose to LOOK on-line. In THIS case I found it rather nice to have someone come on and ask me with assistance.

Very well made but huge
I really like mine. It's so well made, it will probably never wear out. But I find it almost too big and too heavy if filled (I'm a smaller girl.) I think you could fit the kitchen sink in here! I probably should have picked the Half Mass.

This bag is SO big, almost bulky.
The shape and construction are great, I can tell it will hold up. But even with all my law school materials, there is room to spare and the extra space kind of makes the bag bulky.
