Do NOT Hesitate.

I'm not saying "buy it". I'm just sayin' don't hesitate. I hemmed and hawed for at least teo years about getting myself a JavaSok but never could settle on a pattern. During a recent sale, I hunkered-down, made my mind up and clicked the button. And...I really love them! I have one for my brand name Blender Bottle (which also fits several other bottles-as shown), and another for coffee from my favorite little shops (which don't sell mega hunkka sizes), which also fits my reusable straw cup from SBux (as shown) and Shake This Eat That cups (a little extra room in those, but it doesn't pop the Dome lids off, which is quite easy to do). Note-Don't expect/assume waterproof. These are pieces of foam, sewn together. They will absorb some, and need to dry out. They will leave moisture on surfaces if left to sit long enough while cold. But!! Thry do make your hot last a little longer and make your cold last a little longer, and they make for a pretty cup that's comfortable to hold and quiet to place down EVERY time. Sewing construction is super solid, fabric is nice to the touch, and colors are accurately represented in the company's shopping photos. Also, I quite think these colors fit my personal style quite well! One coordinates with my tattoos and clothes, the other with my car interior!
