Best light & slim iPhone 5 case?

Hi,
I'll soon have an iPhone 5 and I'd like to purchase the most slim and light case possible.
What's the best case out there for those who want their phone to remain as thin as possible?

Thanks

There are a few choices, but it does depend if you want a hard shell, soft shell, if you want it clear or not. Speck, Griffin, Moshi, Spigen, Incipio are some of the most commonly sought ones, but there are many choices out there, depending on your personal taste.
