Patagonia Critical Mass Bag

Climbers have haul bags, commuters have the Patagonia Critical Mass Bag. Downsized slightly this season for easier carrying, this bike bag still holds enough gear for a full day without bogging you down. It has padding on the back and along the contoured base to protect contents and provide structure. The main compartment features a drop pocket that secures with a hook-and-loop tab, a mesh pocket for visibility, a padded electronics pocket, pen sleeves and a secure zippered pocket. A padded computer sleeve suspends a 17-inch or smaller laptop off the ground to keep it safe from hard knocks. The front flap overlaps both sides of the bag to thwart rain; it has a pocket that closes with a water-resistant zipper. An external side pocket holds a phone, power cords or water bottle. Its no-slip shoulder strap is fully adjustable, and the waist strap stows away when not in use. With a topside carrying handle, a reflective panel for visibility at night and a bike-light mount. Made of 600-denier recycled polyester with a polyurethane coating and a Deluge DWR (durable water repellent) finish.

great bag
Finally a bag that holds everything I need in one bag, for both me and my dog! I was tired of carrying multiple bags and the critical mass bag carries it all, now I just have to worry about it not being too heavy for me to carry!

Great Big Bag!
I was really surprised by how big this bag is. This bag has a laptop pocket and still enough room for anything else you might want to carry.

Impressive messenger back.
This has all the bells and whistles you could ask for. If anything it is bigger than expected. If uncertain, go for the next size down unless you plan on carrying the kitchen sink.
