G2V Black Neoprene Bottle Insulator Sleeve

I have several water bottles that sweat, so I bought two different sleeves with the idea that they would fit something in my bottle stash. I chose this as one of them, based on the review that says it 'fits a 27 oz. Klean Kanteen perfectly'. With mine, I have to fight tooth and nail to get it on, and now the little binding at the top is coming loose. Could be due to slight variations in size?, but this cover is made with an opening that is smaller than the rest of the sleeve. So it's really hard to stretch the opening enough to get it on most bottles. I do have a smaller water bottle that it fits better, so that's what I'll use it for. It's still a tad hard to get on because of the smaller opening but it works well once it's on, and I'm sure I can mend the tear at the top pretty easily.I still give this sleeve four good stars because it has a fairly sturdy feel, and the actual product description never claimed that it would fit the 27 oz Klean K. The only reason I didn't give it five stars was because the sleeve design (smaller opening) does make it hard to get on the bottles. I can understand the smaller opening to some extent, as it helps it to hug bottles at the top where they taper. But instead of a small opening to make it fit bottle tops, I'm thinking maybe a velcro tab at the top might work better.So back to my Klean Kanteen... I also ended up ordering the Built neoprene capacity bottle tote, and even though it says 20 oz capacity it actually fits my 27 oz Klean K. great! Amazon has it at: http://www.amazon.com/gp/product/B001FUNFZ6I'll be writing a review on that one next.

This fits my 24 oz. Contigo Autoseal water bottle almost perfectly. It is just a little short, less than half an inch, which is not a problem for me. I purchased it because I like to put ice in my water bottle. Not only does it solve the condensation problem but it also helps to keep the water colder and the ice from melting so quickly. It did have a strong chemical scent at first. I just let it air out and after a few days the scent faded enough that it no longer bothered me. It can be difficult to slide on sometimes but I think that is to be expected of this type of item. If it were easy to slide on it would probably fall off during use. For me it is easiest to hold the bottle with the opening up against my abs and pull the sleeve over the bottom of the bottle towards me.

Bought this for my 27oz Klean Kanteen. It is a TIGHT fit. Works well as intended (insulation for cold drinks).I thought it would also fit my 24oz Stanley Utility Stainless Water Bottle, but sadly, it is impossible to get on as the Stanley bottle has a sharp-edged bottom, unlike the curved edge of the Klean Kanteen.Stitching on the little tab where you're supposed to hold on to/attach a carabiner is weak. DON'T use this tab to pull.

It says that it fits on a 32 oz bottle, but the top has a band around the top that does not stretch much, I have a 32 oz bottle that is 11 inches tall and it is about 2 inches below the screw top. I don't anticipate it keeping my drink cold for long. .

Although it was a bit tricky to get on, this "bottle insulator" fits my 27 oz Kleen Kanteen bottle very well and does a wonderful job of containing the condensation that used to get all over the place. Unfortunately, it does not do a very good job of keeping the water very cold.

I purchased this insulator to help keep liquids cold or hot when I needed it. I also needed something to help prevent dents in my stainless steel and aluminum water bottles from dropping them or swinging on a pack. This works great for some protection of your metal bottles, but does little to keep liquids at certain temperatures. If you have cold liquids, it helps with the condensation. I would purchase this item again. Good luck.

It says this is 10.5" tall...it's more like 8". Also, the measurement for the width is taken from laying the product completely flat and measuring it, so it's not the measurement of the diameter of the sleeve. Altogether, it was too small. Fortunately, it fits my mom's 18 oz Hyrdroflask nicely.

I got one in hopes that it would fit our pretty generic metal water bottles... and it does! So now I just ordered more so we can each have one. Sadly, this will only get 4 stars because it's not going to be the best insulator... It will collect all the condensation, which is good, but it really shouldn't be considered as an insulator if you're in a hot climate. It's just stretchy neoprene.
