Bests & Worsts Reviews from Amazon

This will protect your laptop from the inside of your other bag, but not from being dropped. When you drop your laptop, it will probably land on a corner, whether you carry it in a sleeve alone or inside another bag. Unfortunately, this sleeve doesn't really protect the corners. It's padded enough on the "faces", and the corners covered by the zipper have this grosgrain hem (between the neoprene and the zipper) which affords a little cushioning. The story is not as good for corners opposite the zipper: if your laptop pokes between the two inner hems around the edge, then you only have a thin, unpadded layer of fabric at those two corners. When I push into these with my hand, I feel the sharp corner of my laptop. An edge wrap of high-density foam would fix this and deliver much better drop protection. Fit is OK for a Lenovo Thinkpad T450s, though not "perfect" as other reviewers claim, it's a little loose in the "up/down" direction (looking at the main product picture). Nobody seems to make a sleeve specifically for modern Thinkpads, but the T450s has similar dimensions to a 13" Macbook, so I may try out a Macbook sleeve. Finally, why don't more laptop sleeves zip open at the narrow side of the laptop? Most backpacks accept a laptop in the "portrait" orientation, so a narrow-side zipper would let you retrieve and stow your computer without removing the sleeve from your backpack.
