Long term review; I purchased a vertical Mac sleeve in October 2024 and I have been using it daily in a variety of tough conditions. First, the construction of the vertical sleeve is top-notch and feels heavy duty. It is a beautifully crafted and well designed sleeve, but it is also durable and provides nice protection for my Mac. The leather is soft and has already taken on a nice patina. I found that even without a zipper, this sleeve still protects my Mac from drops or collisions; there is extra overhang on the open side the sleeve and I've found this keeps the Mac secure. The wool liner helps keep everything clean as well and I've found the aluminum housing doesn't collect finger prints as badly when stored in the sleeve. The sleeve is also resistant to scrapes, scratches and damage. I've found if a zipper or something sharp rubs against the leather, it is easy to brush out, or I use otter wax leather salve to bring some life back to the leather. I would buy this sleeve again for myself and future devices, but this is my top recommendation for others as well.
