bottlebottle Protective Silicone Sleeve Fit 12-64oz for Hydro Sports,Simple Modern,Takeya,MIRA, Iron Flask and Other Brand Water Bottle, BPA Free Anti-Slip Bottom Sleeve Cover

Bought the size that fits 24oz for our Iron Flask water bottles and it fits perfectly and stabilizes the bottles as I was hoping. Easy to put on. The colors looked nice with the bottles we have, as well. The thickness and quality is just right, while still allowing the bottle to fit in a standard cup holder and in the side pocket of a backpack. I'm planning to buy third for another water bottle.

I bought this after denting my new Hydroflask. It's a REALLY thick cover. Like I was surprised as just how well it held its shape. My only wish was that it was available in more colors, but it seems like its so popular that it sells out quickly. The silicone isn't too tall that it covers up any stickers either.

It was too large for mine, but I gave it my aunt & she loves it. The bright baby blue looks great with her baby pink cup. Flexible but durable material.

Got this because I move around with a cart at work a lot and with my dented water bottle it used to wobble around and make noise, but this slides right on the bottom and keeps it from moving and making a bunch of noise. It cleans great and is super strong, I have dropped my bottle with it on and it protected it just as it should! Easy on and off as well!

Seems to work fine and fits my 20 oz sports bottle.

I bought this specific color for my daughter's water bottle - the color is so vibrant and pretty! The silicone has a super smooth feel and a durable thickness. It's easy to put on, though it would be nice if there was a tiny hole at the bottom to help release the air pocket it gets. It's definitely not an issue, I would still purchase it.Unfortunately it did not quite fit my 16oz bottle. However, I think it was because of the type of water bottle I have. But I loved the color so much that I didn't want to return it. Instead, I switched out the one I had on my Stanley 40oz (of course it fit perfectly) with this one.I love it!

Summary: I used Hydro Flask brand stainless bottles for years, so wanted to compare it to a couple of lower cost China offerings. Also found that my really old Hydro Flasks no longer keep my water cold. Ordered the half gallon (64 oz) by COKTIK, as I kept running out of water on longer work days. Also ordered this Bottle Bottle silicone boot to protect the base.Observations: Hydro Flask is a name brand, and high cost offerings. The typical insulation method at the moment is a stainless steel container, which has a vacuum to provide the insulation. Overtime, if the container is damaged, and the vacuum escapes, the item loses the ability to insulate the liquid. Some common concerns with the China offerings is the quality of the stainless steel, with a frequent concern that lower purity stainless steel will rust/corrode. On my Hydro Flasks that have lost their vacuum, they at least do not show any signs of rust inside. When it comes to the larger sizes (64 and 128 oz), the Hydro Flasks can be nearly 3x the cost, which is hard to justify. Especially given that these larger offerings are more easily damaged if dropped, given the increased weight.Pros: lower cost protection; available in 4 sizes and many colors; cost average to similar offerings.Cons: BOTTLE-BOTTLE has 54  products offered (new manufacturer).Conclusion: At $9, rating this 5-stars.Related Products:COKTIK 64 oz/Half Gallon Vacuum Insulated Jug, ~ $264.7 out of 5 stars    2,435 ratingshttps://www.amazon.com/dp/B0BVM3Q6BM/bottlebottle Protective Silicone Sleeve Fit 12-64oz ~ $104.5 out of 5 stars    4,960 ratings | 122 answered questionshttps://www.amazon.com/dp/B07KWMJJ96/

FIT: POOR, please SEE PHOTOS** 40oz version: DOESN"T FIT - too rounded and too rigid to fit well on the bottle.** 18oz version: FITS PERFECTLY - shaped correctly.The transition between the sides and bottom of my Hydroflask 40oz Widemouth bottle is a relatively square angle, but THIS SLEEVE HAS A ROUNDED TRANSITION. please SEE PHOTO. the rounded transition from the bottom to sides of the sleeve make it impossible for the bottle to slide all the way down into the silicone sleeve. If I force it all the way on, the silicone is too rigid to stretch to fit the square bottom edge and the sleeve works itself off the bottom of the bottle just a little. That leaves this puffy air pocket under my water bottle at all times, which makes it every so slightly unstable when sitting on the counter.Materials: nice, soft / sturdy silicone, bright color. looks great, IF ONLY IT FIT CORRECTLY!!ADDENDUM: in response to the reviewer who suggested it was my application technique that caused the air bubble.I apply and remove the Bottlebottle 18oz sleeve and the Hydroflask-branded 40oz sleeve EVERY DAY when I wash my water bottles, and never have an issue with trapped air bubbles. I find that simply pushing firmly on the bottom of the sleeve during installation will evacuate any trapped air, and I haven't found "burping" necessary. Neither of my sleeves have "vent holes," and both can be used as doggie-dishes.The Hydroflask-branded version I ended up getting for my 40oz bottle is thinner (hence perhaps less protective?), is more flexible, fits more snugly, but most importantly IS SHAPED APPROPRIATELY AND DOESN'T PUSH ITSELF OFF THE BOTTOM OF MY WATER BOTTLE.

El color es Super lindo, y le quedó perfecto

Me gustó tamaño 64oz , material resistente y a la medida.

The silicone sleeve was too large for the 64oz Hydro Flask as shown in the pictures. Got in contact directly with Bottlebottle who would not replace as l bought through Amazon. Now l can't send back as it has taken too long (had to chase Bottlebottle).Paid good money, had to wait for it to come from the U.S. only to find that it is totally useless.Perhaps Bottlebottle should test on the actually Hydro Flask to ensure it fits before shipping....Waaaaaaaaaaay disappointed. :(

Fits perfectly on my 1L Frank Green bottle, stops it clanging on to everything and hopefully protect from dints and scratches. I love the bright colour too

Fits perfectly on my hydro flask!! Protects it well, very durable!!
