The sleeve works great! I fill up my bottle with ice and water in the morning and the water keeps cold well into the afternoon.

I purchased this Water bottle cage with the cage mount adapter as my bike did not come with the proper holes for a water bottle (note to bike manufacturers:  Beach Cruiser users need to drink water too  Anyways, I only purchased one initially (needed one for my lady's bike too) as I wanted to make sure there was not too much slop. Yes, there is a little wiggle but less than I expected based on a prior review.  I have ridden many miles with this waterbottle cage.  I used my Camelbak 1 liter bottle on several trips, and I have also used the standard 16.9oz water bottle.  This cage held the Camelbak bottle at it's full extention and the 750ml bottle fully retracted.  It held both bottles very tight with no worry of loosing them.  It's a well made piece of equipment.

I love my CamelBak water bottle. It has great storage capacity (1L) and i use it too monitor my water intake. I love the drinking spout and i didn't realize it's the same as the CamelBak backpack which i currently own. I highly recommend this product it's definitely worth the price.

Fits my  Camelbak bottle perfectly.  Allows me to put ice in the water without getting my desk all wet.  If it gets dirty, I just run in through the wash with the clothes and air dry.  Great buy.

Holds a 32 oz Nalgene bottle and Olicamp space saver cup perfectly.  It's a little padded so insulates a little. Extra pouch is good for filter straw and water purifying tablets.

I recently purchased a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/G2V-Products-17-5-Ounce-ZERO-MASS-Stainless-Steel-Drinking-Bottle/dp/B003R7JBI0/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">G2V Products 17.5-Ounce ZERO MASS Stainless Steel Drinking Bottle</a>&nbsp;and decided to buy this sleeve to go with it and I am very happy that I did. Not only does it keep the bottle cold and dry it also protects the finish of my fairly expensive sippy-cup.  I couldn't be happier with it.

Very nice vacuum insulated 64 oz water bottle.  Nicely packaged (reminds me of an Apple product) and as an extra nice touch you can put one of 6 or so different colored 'rubber' decorative bands around the lid of the bottle to personalize it a bit more.  Good satisfaction email follow up and good performance to date.  I also bought the cloth carrying bag that fits this bottle very well and is quite handy.  Overall a good product.  I use this on day long trips as a refill bottle for a smaller water bottle that I have.

Bought a new standard 40 oz water bottle. Bought a new 40 oz carrier to carry it. This fails - the sleeve is too small for the bottle to fit in.  Perhaps mislabeled.

The sleeve itself is well insulated and fits the 40 oz Hydro Flask well.  It also fits the 32 oz bottle but its stops a inch before the top of the pouch.  If using the Hydro Flask wide mouth straw lid with the 32 oz bottle is should work fine.  The strap is low grade webbing but I bought the pouch not for the strap but for the pouch itself.  I plan to get a better strap that clips on and is longer.  The Pouch itself is heavier than I thought, but it is insulated.  If weight is an issue that may be a concern.

My wife uses this every day. The sleeve keeps the water very cold. She has left the camelback bottle with the sleeve on in a car for a couple of hours in the Texas Summer Heat and when she got back to the car it still had ice. When she uses this at work ice stays in it all day.;

This is a moderate-sized glass bottle which fits into the protective Neoprene jacket. The lid has a snug fit and the handle is there if you want to use it.  It's a bit more attractive than most similar water portable water bottles. The Neoprene protective jacket is well designed so that it does its job in protecting the bottle.  I like the purple color personally.

This bag was a drop in replacement for a 2L Camelbak bag that grew a bit of funk.

It held water just fine and the wide mouth made adding ice simple. The insulation wrap around the hose was a bit thin but it kept the first sip cool even in 88 degree heat. The couplers were leak free and carry handle was nice and sturdy for a 2L fill up.

The bite valve was a bit loose when i received but I resolved the issue with a pair of zip ties and it held up just fine for a weekend on the mountain. If you plan on using this bag it might be worth grabbing a hose clamp as the bite valve is press fit onto the hose.

Overall a great bag at a great price.

My husband uses it to carry a 1,5 liter (48 oz) water bottle. It stays fresh and it's easy to carry.

Others have already covered the pros & cons of the Neosling water bottle holder. We have a lot of different water bottles at home and I just wanted to list out some of the more common bottles that fit in this Neosling so you can get a better idea of whether this is the right size product for you:

STRETCHES TO FIT
(definitely won't slide out of sling):
-- 32oz Nalgene bottle
-- 1000mL (~32oz) Camelbak bottle

FITS
(may slide out, but I haven't had a problem since I adjust the sling to a comfortable height so that the bottles pretty much stays upright):
-- 18oz HydroFlask bottle (stainless steel insulated)
-- 750mL (~24oz) Camelbak bottle
-- 25oz Camelbak Big Chill (insulated sport top)
-- 20oz Polar Bottle (insulated sport top)
-- 24oz Polar Bottle

FITS LOOSELY
(these bottles are narrower and will definitely slide out if inverted):
-- 16oz Nalgene bottle
-- 500mL (~16oz) Camelbak bottle
-- 22oz Thermos bottle (plastic push button top)

The strap easily adjusts for both tall & short people. My 9yr old has no problems adjusting it for shoulder carry or cross-body carry. The only improvement I can think of would be to add some sort of way to cinch up the top opening of the sling to ensure that the smaller/narrower bottles don't slide out.

Holds around 2 liters , I wash the bag out with water and a little bleach before use.... I like to put bottle water (4) and ice and it stays cold for a long time.

This is a great sleeve for the Hydro Flask 40oz bottle.
I'd give it 5-stars if some of the appropriate parts were metal rather than plastic.

A great bottle cover for my Nalgene and my Camelbak waterbottle. Fits perfectly with no issues although it works better for Nalgene than for Camelbak because of plastic ring on the bottle that can be attached to the bottle so that when the cover is removed, it is leashed to the bottle. I absolutely love this water bottle cap. This a great buy to be able to reduce the size of the drinking spout but to be able to to remove the drinking part and have the full size of the top to fill up your bottle.
