Review: I love it!!! - Works great and looks wonderful with the colors on the logo and the cup itself!!! It fit nice I did flip it inside out to put it on but that’s what I figured would work best to get it on snug!! It’s not too thick where it doesn’t fit in my cars cup holder either just need a little more strength to pull it out of it but it’s not gonna fall out and that’s what matters!! I use on the lighter purple one and my boyfriend has the clear one and that one also looks good with his navy blue cup!!
Review: Great idea - Fit my Stanley well and covers up the peeling paint on the bottom of it.

Fit my Stanley well and covers up the peeling paint on the bottom of it.

### ⭐⭐⭐⭐⭐ Great fit and beautiful colors – 16oz water bottles
*by Y***. on August 26, 2025*

These silicone bottle boots fit perfectly on my daughters’ two 16oz water bottles. They were super easy to put on, stay in place, and protect the bottom really well. The colors are beautiful in person and look exactly like the pictures. The material feels sturdy and good quality, so I’m confident they’ll last.
