Incase has just released a new leather version of the Nylon Sleeve Plus model we showed you a couple weeks back. The Black Leather Sleeve Plus is designed to hold a 15″ MacBook Pro and offers a refined material combination of Nappa Leather and Ballistic Nylon. A great option for those looking for a more stylish way to transport and protect their laptop. Incase has also released a sneak peek at their first iPhone case. Check out more images after the jump.
