maharishi roller

http://www.dpmhi.com/productdisplay.php?item=5
-i've seen this with my own eyes. easily the most bling of rolling bags. huge pockets and the 3 huge wheels for climbing stairs and anything else. they put a huge amount of thinking into it. every little hidden pocket and zipper is well designed. kevlar corners so it won't get bashed up. i only wish it were cheaper. you can buy it at the convent garden maharishi store in london.
