Chrome's new Lieutenant rolltop messenger bag combines the versatility and easy access of a messenger bag with the watertight seal of a rolltop backpack to make one tough bag. Doesn't hurt that it's got looks, to boot.
The interior is fully lined with box-welded, military-grade truck-bed liner to ensure a waterproof seal that Poseidon himself would struggle to breach. This means your 17-inch laptop and other goodies stay dry when it's wet and miserable outside. Conversely, when it's warm and sunny out, feel free to throw in some ice and a six pack -- the waterproofing works both ways. Even better, its dual interior compartments mean you can have beer, ice and steaks in one compartment and a sweatshirt and iPad in the other. If that's not progress then you need to lower your expectations.
Other features include a quick-release strap buckle with a built in bottle-opener and large exterior pockets for easy access to your lock, keys, phone, whatever. It's made in the US and available now for $US180. [Chrome via GearJunkie]
