Not disappointed, it's a great little bag. It's not going to take just any bottle, but it's fine for both of mine (Vargo Titanium 22oz. nestled inside the Vargo 450 travel mug, and a 27 oz. Klean Kanteen with loop cap). It also fits a 24 oz. Zephyrhills water bottle. There's width to spare around each of these, so it can take a wider bottle, but maybe only a little taller.I haven't used it in the field yet, but it appears plenty durable. I didn't find any loose stitching or rips like the one commenter. It's nice that it insulates, and that it has an additional outside pocket, and that it is versatile in carrying configurations. I'm not going to use the removable patch, but if it weren't removable I wouldn't consider it obnoxious, but that's subjective.The outside pouch will hold my Pixel phone plus some light treats. The photo shows two power bars, a quarter of a package of nuts rolled up, and my phone, plus the Zephyrhills water. Inside you can see how much room there is for a slightly wider bottle. It all closed up nicely with all that stuff in it.It will be great for walking the dog and other short hikes or bike rides. Anything more than that and I might want a little day pack or something. But even for robust backpacking trips this is a great way to augment hydration. I can either attach it to my pack or my belt, or shoulder carry it, whatever. This is perfect for what it is. And damn, when I bought it it was $4.95 - no brainer!! Now I see that it's $9.95, but still it's a no brainer.
