Dr. Brown’s ナチュラルフロー® オプションズ+TM 細口ガラスボトル用シリコンスリーブ、ミント、8オンス

Dropped this sleeve on the tile floor twice already and the bottle didn’t crack—the silicone absorbs the impact way better than I expected. It also stays put on the glass when I’m warming the bottle, no sliding around.

It’s nice that the sleeve comes off easily when I need to sterilize everything, since I was worried it would trap milk residue. Only gripe is that the mint color looks slightly lighter in person than online, but the grip on the bottle feels secure enough for my wiggly baby.

The silicone is grippy enough that I don't worry about dropping the bottle, even with wet hands. Only reason for four stars is that it's a bit of a struggle to get off for cleaning, but it stays put during feeds, which is what matters.
