Proactive Sports Neoprene Bottle Holder with Drawstring and Bag Clip for 16-20oz Bottles

I've had this for only a few weeks, and used it three or four times a week. So I can't claim that it is durable, but it certainly does look like it is. I can claim that it keeps a cold drink cold for at least six hours in room temperature air. I have not tested extensive exposure to hot summer air.The typical 20 ounce soda bottle is a perfect fit. A drawstring at the top can be pulled tight over the top of a bottle by adjusting a toggle, closing the only entry point for air.The drawstring seemed longer than needed, and the plastic clamp at the end sometimes bothered me a little bit. So, for this review, I took a closer look at it. It turns out the clamp is easy to open. If the ends of the drawstring start to fray, and the clamp won't hold, it opens easily with a finger nail. The frayed ends could be cut off and the clamp easily put back on - a nice feature for extending the life of the cozy.There is also a clip at the top of the cozy that fits easily onto a belt loop. The clip is all of plastic, and the part one would press to put it on a belt loop (or something else?) feels like a strong spring. It, too, looks durable, but I probably won't be using it.If I lose this cozy, I would not bother to check out others, but just buy another one.

I drive school buses and this works perfectly for my beverages on the bus and fits in the cup holder nicely!!

I really like it keeps my drink colder longer. Wish the draw string would close the top around my bottle tighter or the sleeve was a tad bit longer.

Works well keeping liquids cold and me hydrated on the golf course.

Neck needed some alterations to stay tight around soda bottle.

Overall satisfied purchase, keeps drink I bit cooler for bit longer

Doesn't keep beverages cold as long as I hoped but does keep sweating under control and is comfortable in the hand.

Nice and thick but still fits in the cup holder. Strap and clip is handy. Keeps my drinks cold.
