Medium boot for my water bottle 40oz friend. It has a good grip, not loose like the cheap knock-offs, and decent thickness. It has for real saved my bottle from dents and scratches from all the times I have dropped it.

Awesome for protecting the bottle! I love that it matches the color of my water bottle perfectly and is super grippy for leaving on the table. Prevents a loud noise when dropped too!

Nothing special just a boot. It fits well on it. I have a lot of wood surfaces in my house and it really helps not scuff anything up when I set my bottle down.
