I just received the brand new iphone sleeve from Freitag for my iPhone 5. In my humble opinion they are one of the best sleeves out in the market. The sleeve is very durable, stylish and unique and does not add too much additional height to the iPhone. For sure, you do not get it for free (60 CHF, approx. 50 EUR), but its worth every cent.
So if you are still looking for a cool christmas present for a new iPhone owner, this could be a valid option! 🙂
Cheers,
Brian
