Review: Protective and not bad to look at - Does a great job of protecting. Also love the fact that it dampens the noise of when you put the hydro flask down or hit it slightly.
Review: Does the job - I bought this to put on my Yeti Rambler to prevent any dints because I’d paid soooo much for it. Does the job fantastically. Fits my 36oz rambler perfectly

## Questions & Answers

**Q: Will it fit onto a yeti 36 oz vacuum bottle?**
A: Hello, honestly I don’t know. I have the 32 oz and the 40 oz and it fits perfectly. I don’t have a yeti but if they’re the same shape, you shouldn’t have a problem.

**Q: will a medium-size flex boot fit a 40 oz bottle**
A: I have a 40oz wide mouth Hydroflask, and it fits perfectly inside the Medium size flex boot.

**Q: Will I need to remove it before cleaning?**
A: It’s necessary - but I just took my boot off and found a bunch of sand in it!  Clean it once in a while:)

**Q: what does size 1 count mean?**
A: Hi Lori - Wendy here from Tall Ridge, the exclusive authorized seller of Hydro Flask products - Thank you for your inquiry! I'm so sorry for the confusion! We've been having some technical issues with our listings and Amazon is working with us to correct them. '1 Count' is for the medium-sized boot. I hope that is helpful!
