Olababy Silicone Sleeve for Philips Avent Glass Bottles
4.6 (21 verified reviews)Why it works
Purpose-molded for Avent Natural glass bottles — protects against drops and heat transfer while keeping the measurement marks visible.
Details & benefits
Glass bottles are the safest material — and the easiest to break. Parents who choose glass for purity trade it for slippery grip, breakage anxiety, and hot-to-the-touch warming.
This sleeve is molded specifically to Philips Avent Natural glass bottles (4oz and 8oz). The textured silicone adds grip for parents and babies, cushions drops, and insulates hands from warmed milk — while a measurement window keeps ounce marks visible.
Proof it works: One of Olababy’s most-searched products — ranking top-5 for Avent sleeve searches because it fits like it came in the box.

Our material
“Food-grade silicone” is a purity standard, not a marketing phrase. Olababy uses 100% high-purity food-grade silicone with no fillers, free of BPA, PVC, lead, and phthalates. Unlike plastics, silicone is inert: it doesn’t leach chemicals when heated, sterilized, or chewed on, and it stays soft on developing gums and teeth. Every batch is tested to FDA food-contact standards, and every product is dishwasher-safe.
