Vỏ silicone bình thủy tinh cổ rộng Dr. Brown's Natural Flow® Options+TM

The silicone sleeve is grippy enough that I can hold the bottle one-handed while rocking my fussy baby—no slipping at all. It slides off easily for cleaning too, which I appreciate after every feed.

Dropped my glass bottle twice in one week before I got these, and the grippy silicone grip makes a huge difference. They slide on and off easily for cleaning, so I don't have to wrestle with them every time. Baby seems to hold it way more confidently now.

I was honestly dreading how slippery glass bottles get when they're wet, but these sleeves have fixed that completely. They slip on and off easily for cleaning, and the grip is secure enough that I feel confident handing the bottle to my toddler.
