As an admitted computer bag fanatic, I have a special affinity for the creations of WaterField Designs in San Francisco. I personally use one of their bags (the Travel Express) to carry either my MacBook Air, two iPads, or the MBA and an iPad. That bag has gone through a lot in the last three years, but it still looks like it just came out of the box.

When Heidi the PR lady at WaterField Designs told me about the line of new bags that they've specially created for the Retina display MacBook Pro, I decided to jump on getting some review products to try out and to give away to TUAW readers. In this review, I'll talk about both the Smart Case (US$99.00) and City Slicker ($149.00) for the 15" Retina display MacBook Pro, and then at the end you'll have an opportunity to win one from TUAW courtesy of WaterField Designs.

Smart Case

Let's start with the Smart Case. While it's not a total "bag" for your Retina MBP, it's designed to offer protection to your baby while you toss it into a briefcase, backpack, or any other larger bag.

What's great about the Smart Case (as with all of WaterField Designs' products) is that it has padding everywhere you can imagine. There are high-impact rigid plastic inserts to keep your MBP safe from bumps and bangs, and it's cradled inside an Ultrasuede liner.

The outside of the case features water-resistant nylon in a choice of six colors -- black, pearl, pine (dark green), green, flame (orange), and copper (tan). There's no stitching visible on the outside of the case, and the sides are encased in distressed brown leather trim. On the back side of the Smart Case is a stretchable pocket for carrying your power adapter and other cables.
