There are a few qualities that push the price of tech accessories up, including the use of real leather, and being assembled in America. Waltzing Matilda’s Avery Sleeve ($160) might make more sense, then: the expensive envelope is all real cowhide, 100% American sourced, and manufactured in the USA. And should be the case for the price, it looks really nice.
Two shades of brown leather are available, and Avery comes in 13” and 15” variations. A top flap folds down about three-quarters of the way, and a strap wraps around the body to hold everything in place. It’s designed to age with time, so don’t worry about keeping the sleeve pristine while it protects your Mac. Oh, this one’s an Apple Online Store exclusive, so you’ll have to order it and have it shipped to your home, or your local Apple Store.
