## Questions & Answers

**Q: Is the protective boot available for the 64 oz bottle?**
A: Hello,
We are working to introduce a 64 oz protective boot to the market by early 2020. Thank you for your interest!

**Q: Will this fit the kids 10oz bottle?**
A: Measure across the bottom of the bottle.  If it has a 3  1/2 diameter, then yes, it will fit.

**Q: Is there a protective boot for the 64 oz bottle yet?**
A: Not boots but I have a Molle-like bottle holder or sleeve for mine. It has a pocket, shoulder straps and a handle. Search Amazon. That's where I found mine. I think I looked for 64 oz bottle sleeves. But try searching under different names too, like grogs, beer kegs, etc.

**Q: Is there a full bottle sleeve? I've knocked walls and my car with my flask now and a full sleeve would be nice to protect things from the bottle.**
A: We do not have a full bottle sleeve available at this time.

### ⭐⭐⭐⭐⭐ Highly Useful!
*by K***� on September 10, 2025*

Fantastic! This is great for a big water bottle! Keeps it quiet when moving it or sitting it down in a quiet room. Prevents scratches and dings all around the bottom and some protection on the side if it gets knocked over. Easily cleaned with hot water and soap. Would definitely purchase again 10/10!
