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.
1 silicone sleeve (bottle not included).
100% food-grade silicone — BPA, PVC, lead, and phthalate free. Dishwasher safe (top rack). Designed in Portland, Oregon.
