Question: what is made this bag?
Document: It size is perfect for a netbook or iPad the bag that has at the front help you to place all the cables, it's color is wonderful and excellent material.
These are so well made and the color is just awesome. They are nicely padded with a place in the pocket for a usb drive even.
I use this neoprene sleeve over top of a plastic hard case for my iPad. The neoprene is water-resistant so spills don't do damage and the slick sides make it easy to slide in and out of my bag. This case is big - plenty of room to go on over the top of the protective case.
I know "great zipper" sounds like an odd compliment, but seriously, there's nothing I hate more than a thin, difficult to find zipper that gets caught when you try to zip your bag up quickly.This little bag is just awesome -- my favorite sleeve of a few I own.PROS:- The material is soft, thick, and strong.
Case fits great for my Asus Transformer Prime (TF201) with keyboard dock attached. Can easily put the charging plug in front side pocket with some room to spare. While I've only had it for 2 weeks, the case is well made and has good padding for protection.
Love the color, Love the case, REALLY Loved the price. I bought this for my new iPad because I wanted something to protect it when I needed to take it inside another bag. The color is great and the outside zip pocket is roomy and easy to access. This sleeve is slightly larger than my iPad so the fit is good even with the keyboard cover. There's also room for my Kindle too. Really love it.
This is the only downer for this product. Thus, I give the product 3.5 stars, but round up to 4 because......the zippers seem extremely well made, which I think bodes will for the longevity of this product. Case logic, for years and years, has made very STURDY cases for cassettes, CDs, etc. etc.
(Zips open across one long side and about 3/4 way down one side, but the other side only zips open 1 inch.) I would prefer that it zip open flat; it would just be nice to have that option.- No handle of any kind (not even a finger loop)  :-(Overall, nice case, love the side pocket. Wish it came with even one little finger loop or ANY way to grab it out of a bag or secure it in place.
This item appears to be well made, however, the color is not the same as the picture shows. It's not a dark blue, it's more of a green/blue color. I think the picture of the product should be updated so it's correct. The color is still nice. It looks like something that a girl would like, more than a guy. It's a little feminine in color.Its a nice case that can be used to store other items besides a Netbook.
This is definitely better than my current netbook case, a Vera Bradley number which looks cute but  is  much flimsier by comparison. All things considered, this is a well-made item that offers better protection than other comparable items currently on the market  and has a sleek and appealing look to it. The list price from Amazon seems high, but I'm not sure it is realistic. I'd suggest trying some comparison shopping before buying.
Answer: Neoprene is my best guess.
