I honestly love this laptop sleeve. It's really thick all around, made with some sort of really durable fabric. Not sure what it's called, but if you tried taking a knife to it, it would take some effort to cut through. Also, the inside is lined with this really soft fleece. It's impossible to scratch your laptop when it's inside here. It fits my Macbook Air really snug. When I bought it, the tag specified it was for the Macbook Air, which I may have missed while reading the description. So if you have any other kind of 11-inch laptop, make sure the dimensions are similar to that of a Macbook Air. Otherwise, I'd say Herschel's product quality is genuinely trustworthy. I would've easily paid around $50-60 for a case this nice.
