I was worried the boot would slip off, but it hugs the bottle perfectly and the grip is noticeably better when I'm carrying it to the gym. The two size options meant mine fit exactly right with no loose ends.

The silicone texture makes it way easier to hold my bottle one-handed on morning runs, and the fit is tight enough that it doesn't shift around. It's a small upgrade that just makes sense.

The boot snaps on snugly and the two size options meant I didn’t have to guess—fits my travel bottle perfectly. It’s already survived a few drops on concrete without a scratch, and the texture really helps when my hands are wet.
