Frezonika 4-Pack Koala Silicone Sleeve for Dr. Brown Narrow Glass Bottles 8 oz

Protective, Playful, Practical: Frezonika Koala Sleeves

Frezonika's silicone sleeves wrap snugly around Dr. Brown Natural Flow narrow-neck glass bottles, including the 4 oz and 8 oz sizes. The koala shape adds a friendly touch while a precise fit helps keep the bottle within easy reach for caregivers and little hands alike. Note that this sleeve is designed for narrow-neck models and is not compatible with wide-neck bottles.

Beyond the smile-worthy design, the sleeve features several practical details intended to support everyday feeding routines. The soft silicone can help retain warmth on a chilly morning, while a reinforced 5 mm base cushions impacts in case of a gentle drop or bump. Built-in loop handles encourage babies to grip more independently, reducing slips during lively mealtimes. Small side cutouts provide a quick milk check without removing the sleeve, and the material is BPA-free and dishwasher-safe for simple cleaning.
