Mommy Cha loved her Moby wrap so much that she brought Moby to Korea. The website is in Korean. The front page has English, but when you click on the links, all the relevant information is in Korean. They just launched so they may be working on an English version of the site later, but if you want to buy, now, you may need someone that reads Korean to help you.
If you want to see the Moby Wrap in person, Moby Wrap Korea got a last minute booth-entry in to the Coex Baby Fair (August 20-29, 2009).
The great thing about Moby Wrap Korea is that Sarah really knows how to use the wrap and can help you learn to use it well. In the babywearing circles, I've found that wrap lovers are diehards. They REALLY, REALLY love wraps. Everyone who loves them says they are so easy to use, but my eyes just glazed over when looking at the instructions. Since I had trouble getting my baby positioned in a ring sling and had no experienced babywearers around me, I went a soft-structured carrier.
However, at Moby Wrap Korea, they even have Moby Wrap Meetups where parents and babies get together for fun activities so you could get hands-on help. Once you learn how to use the wrap it becomes second nature. It still takes longer to put on and off than a soft structured carriers, but it folds up small and adjusts well to all kinds of body types.
