Ortlieb Velocity

The Ortlieb Velocity backpack is a top pick for commuters, especially those who bike to work. It is completely waterproof and sports a unique roll-top design that seals with velcro instead of a zipper. The 1,220-cubic-inch backpack has a removable inner pocket to hold smaller items, and the padded back panel is ventilated to keep you cool on your way to work. There are six color options, but the bright yellow helps increase visibility. Reviewers say the Ortlieb Velocity is very durable; one reviewer reports commuting with it for over five years. It's not the cheapest backpack on the market, and some reviewers would like an external pocket for easier organization. Still, the Ortlieb Velocity gets a number of recommendations for those looking for a lightweight and waterproof commuting backpack. If you need a backpack with a laptop sleeve or compartment, The North Face Recon (*Est. $90) is a well-reviewed option. It's a similar size and weight as the Ortlieb Velocity (although the Recon is a bit deeper), but the Recon includes a padded laptop sleeve.

The Ortlieb Velocity is featured in a number of backpack reviews, but the best come from Bicycling magazine and Wired. Their reviews are based on personal testing. The Velocity backpack is also reviewed on CBS' "The Early Show," but it's not tested or compared with other packs.
