This product is exactly what I expected from a laptop sleeve. The material is nice, the pockets are the perfect size, and the case feels solid enough for me. Material: First, let me say that I know nothing about material types. If they showed me stuff, I wouldn't know which ones are vinyl and which ones are velvet. What I do know is that this shop is nice. It says it's a neoprene sleeve and I'm assuming that's true. What I do know for sure is that it's a lightweight, comfortable fabric that doesn't seem prone to ripping or tearing. Storage: This case is perfect for my Lenovo S10-3T. I keep my laptop in a large bag along with all the paperwork I need to take to class, and the front pocket is big enough for a charger and mouse so I don't have to use the ridiculously small touchpad on my laptop. Reliability: I've been using this case for over a year and haven't had any breakage or tearing issues. The case seems great for me and my friend who has the same case. Neither of us uses a shoulder strap, so I cannot confirm the reliability of this item. The bottom line is that I bought this suitcase and the day after I got it I had to order another one for my boyfriend because he loved mine so much. It's absolutely minimalist. It contains what I need and nothing else. As far as I can tell I will never have to look for a laptop bag again unless I buy a larger laptop.
