Good, but need to be a little taller.Took these with us to the o.c. fair . We put a half frozen water bottle and slipped it into the sleeve @9am and @ 5pm with 85° weather the water was still more than slightly fzn! These sleeves work great!!Wanted to make sure we didn’t loose our water bottles! Attached to back pack! Worked well!!!Works great for my cupsCleans easyThese are a great size but the stitching is not durable. I used embroidery thread to reinforce all the stitching. Other than having to remake them, these worked very well for a school trip to Europe. It was easy to keep our water bottles connected to our backpacks.I love the different color, gave to friends for a girl’s trip. It made it easy to identify and the carry handle was convenient. The silicone insulation kept drinks cold.Just received the item. Have not had to wash them yet, but they seem to serve my purpose.Very nicely done neoprene carriers that fit the 500ml water bottles perfectly. I kept two of the carriers and gave my husband the other two. He likes his water chilled, and I'm ok with room temperature. The water (or other drink) stays for a good several hours at the same temperature it was when first put into the carrier.I like the clip-on handle; it lets me clip my carrier to my work bag at work, or the belt loop when I'm out and about. Good product, good price, very fast delivery - very happy!It's easy to clean, I just throw it in the washer. The locking plastic does have a tendency to bend down over time, but you can easily bend it back into place, so no real problem. It holds my Brita filter bottle well, protecting it from scratches and dings if dropped. Adds an extra bit of insulation to your drink.The fabric is durable but the seams could use some reinforcement as I use sleeves daily for my tea travel mugs so they don't get scratched up when I throw them in my bag and these are starting to separate. I will likely need to touch up the seams to continue using. The clasps seems to be strong enough when clipped to a bag. Can't beat the price for 4 color options so it's still a good deal.Buy these for my children's water bottles they keep their water cool, stop condensation on the outside of the bottle and protects incase dropped. Have been using bottle sleeves for a couple of years. Pink one would be nice a bit darker.Nice water bottle covers with a handy carrying strap. the colours are true to the picture and a standard, reusable water bottle fits snugly inside. The clips are easy to open and close. Can't speak to the durability of either the clips or material yet, but so far they are exactly what I expected.Update - Not a huge issue, but one of the straps let go on the first use. No biggie - a needle and thread takes care of it. But, a disappointment that led me to lower my rating.
