TUAW has reviewed a number of the high-quality bags from ECBC in the past; their Poseidon Messenger Bag was a favorite of mine, and the Dart Laptop Tote is perfect for smaller Apple laptops.

Today the company announced the new K7 Color Collection, bringing the tough ECBC design to a colorful group of bags that are perfect for everyone from travelers to commuters.

The K7 Color Collection is made up of the Thor Laptop Backpack (image above, US$119.99), Hercules Laptop Backpack ($139.99), Poseidon Messenger ($99.99) and Zeus Messenger ($119.99). All of the designs are available in Berry, Green, Linen, Blue and Black for shipping today.

The Hercules Laptop Backpack is of special interest to frequent travelers, as it has a TSA-compliant back panel that unzips for easy inspection of your laptop.The K7 Color Collection is made of water-resistant 1000 denier Kodra for extra resistance to scratches, punctures, or tears.
