Built with military grade materials and a welded waterproof main compartment, the Chrome Soyuz Messenger Bag is a rugged commuter pack that's guaranteed for life. Its abrasion resistant cordura fabric withstands daily wear and tear, while the tarpaulin lining keeps outside moisture from seeping through. The welded waterproof main compartment is great for holding work documents, school textbooks, and other sensitive items. It also doubles as a handy beverage cooler, thanks to its tarpaulin lining. Another cool feature with this versatile commuter pack is the water resistant, side access laptop compartment. This compartment protects your laptop from soaking showers and nasty weather when you're biking across town or walking through campus in inclement weather. Other key features include a front organizer compartment for storing your U lock, wallet, writing utensils, and other daily items. Furthermore, the compression molded back panel and air mesh shoulder straps alleviate pressure points when you're carrying heavy loads.
