## Customer Reviews

### ⭐⭐⭐⭐⭐ Great protection!
*by J***Z on November 29, 2018*

I saw this cover on a customer who left their 40 oz Hydroflask bottle at my work. Thought it would be great for myself and especially for my son's bottle since he uses it at school and drops his often. Teachers hate the clanging sound of the metal water bottles so thought this would be great to prevent any noise in the classroom and to prevent any more dents. Our particular cover is being used on a 40 oz Takeya active insulated bottle. It fits perfectly.You need to really follow the directions it comes with in order to properly put on the sleeve onto the bottle. It is a tight fit and It's a mini workout putting it on, but it does what it's supposed to do. Taking it off to clean takes effort too but in the end it's worth the money to protect the bottles from dents and scratches.Glad I saw this and was able to find one for my brand of bottle. Please do read the description on what sleeve you select and what size and brand it fits for your particular bottle because not all sleeves are compatible with all brands.

### ⭐⭐⭐⭐⭐ Five Stars

Great protection and bumper for your Takeya 40 oz water bottle! Will work on Hydroflask, too.PURCHASED: September 2017UPDATED REVIEW: August 2020I purchased 4 Thermi Protective Sleeves in black, midnight blue, camo green and translucent gray (and 4 Oonla Protective Sleeves in Blue, Purple, Pink and Translucent Glow in Dark) for our 40 oz Takeya Water Bottles in September 2017. My family of eight (1 young child, 2 teens, 2 young adults, 2 adults and 1 senior...1 teen, 1 young adult and myself are female.) We are an active family who lives in Arizona and travel frequently. We use our water bottles w/silicone sleeves year round...never leave home without them...never go outdoors without them. We have taken them on road trips to California, Nevada, Colorado and throughout Arizona. We have taken them on trips to Hawaii, New York/New England, D.C., Florida, Louisiana and Texas (different climates hot, humid and cold.) We take them to the beach, lake, hiking, events, amusement parks, sightseeing, movies, shopping and school/church. A couple of them have been dropped, kicked, stepped on and tossed around. They have been washed on and off the bottles many many times. We do not have any issues with the sleeves stretching/expanding and sliding off...no tears or cuts in the seams. They are still in excellent condition!I felt the need for a rebuttal to a couple of other reviews I recently read when shopping for two more sleeves for two bottles I purchased for another daughter and her husband.They can be difficult to put on and take off...try doing so while rinsing/washing the bottle...it makes it easier! They have protected our bottles and held together for the last three years.pic: 4 of our 8 bottles today (other bottles being used at time of pic!)

### ⭐⭐⭐⭐⭐ Fits perfectly!
*by A***T on October 9, 2018*

After receiving a hydroflask for my birthday, I was nervous of denting it as I can be a bit clumsy. I searched amazon looking for a silicone sleeve which would provide protection in case of an accidental drop. I came acoss Thermi and my interest was peaked. I decided to order one as the price was exceptional. The product arrived within two days and I was excited to try it out. It is a perfect fit to my 32 oz hydroflask. The quality of the sleeve is exceptional and I no longer worry about dings and dents. The silicone is a perfect thickness which is thick at the bottom and thinner at the top. I have since dropped my bottle on accident twice from about 5 feet up and upon examination, my hydroflask was protected completely. I highly recommend this product!
