WaterField Designs has added a 15-inch Rough Rider Leather Messenger bag to their line-up. After releasing the 13-inch version, the company says it had a “ton” of requests for a 15-inch model.

The Rough Rider is constructed of naturally tanned, full-grain leather. Its strap compresses bag contents to maintain a slim profile. The laptop bag rests against your body, helping ease back fatigue, says WaterField CEO Gary WaterField.

The main compartment can house a laptop, files, chargers and other necessities. There are two deep, waxed canvas pockets in the main compartment. Plus, there are two lined pockets under the flap for storing items like an iPhone or iPad mini.

The 15-inch Rough Rider Leather Messenger costs US$355; the 13-inched is $335. Go to www.sfbags.com for more info.
