I need a Macbook Air 13" Sleeve Recommendation!

With my old Thinkpad T61, I had this GREAT sleeve called the Zeroshock III: http://www.netbookchoice.com/2009/08/24/nbc-zeroshock-iii-netbook-case-review/ Img_6237_medium

It was a fantastic sleeve with great padding on the inside, water resistant exterior material, thin and light, and fairly rigid.

Now that I have my Macbook Air, I want something similar, but the company doesn't currently make a version.

So anyway, post your sleeves and your impressions of them. So far I haven't been impressed with what the local Apple store has in stock!
