Dr. Brown’s Natural Flow® Options+™ 細口ガラスボトル用シリコンスリーブ

The sleeves slide on and off easily when I need to sterilize the bottles, but once they're on, they stay put and give a nice grippy hold—even with wet hands. My baby can clutch the bottle without it slipping, and the glass feels way less precarious.

Dropped one of these on the kitchen floor twice already and the glass didn't chip — that removable 100% silicone sleeve really grabs the bottle and cushions the landing. Feels solid in my hand, and it's simple to pop off for a quick rinse.

The silicone sleeve is grippier than I expected, so my baby can actually hold the bottle herself without it sliding out of her hands. It fits snugly over the glass and comes off easily for washing, which we do constantly. Definitely worth the peace of mind for the inevitable drops.
