The sleeves pop off easily for washing, which I appreciate several times a day. They add a nice grip so my hands don't slip when the bottle gets wet, and the glass feels much more secure for my little one to hold.

Pulled one of these on right after washing the bottle and it slid on easily but stays put once it's on. The silicone is thick enough that my baby's dropped bottle didn't shatter on the tile floor, which is all I really needed.

The grip on these is fantastic—my hands don’t slip even when washing bottles with soapy water. The silicone feels thick and durable, and popping it off for a quick rinse is effortless. My glass bottles feel way more secure now.
