The sizing of this Amazon laptop sleeve is totally incorrect. I ordered 15.5inches sleeve for my 15inch laptop and I got this 18inches laptop sleeve, which is way too big. I sent it back for exchange thinking they have dispatched the wrong size. But, even after exchange I got the same piece with exactly same measurements. Which means you have to order 3 inches smaller than the actual laptop size. This sleeve is huge... I can use this as my weekender... Sizing gone wrong totally. Wasted my time.
