Plastic-Free Glass Baby Bottle
Borosilicate glass with a 100% natural rubber nipple - the zero-silicone dream, undercut by a polypropylene screw ring and cap.
Plastic-free verdict: Minimal plastic contact
The standout part is the nipple: 100% natural rubber, so the soft milk-contact piece has zero silicone AND zero plastic - rare and exactly what zero-silicone parents want. But HEVEA states the leak-resistant screw thread (collar) and dust cap are polypropylene, and that screw ring seats in the milk path. So the drink does touch a bit of plastic. If the ring were steel or rubber this would be a plastic-free standout; as sold it's minimal-contact with an excellent nipple.

A borosilicate glass baby bottle from the natural-rubber pacifier brand HEVEA, fitted with a one-piece 100% natural rubber nipple that has the anti-colic valve built in (no separate plastic vent parts). Sold in standard-neck (4oz, 8oz) and wide-neck (5oz, 8.5oz, some with a silicone sleeve) versions. The natural rubber nipple is the reason to buy it; the screw ring and dust cap are polypropylene.
Pros
- 100% natural rubber nipple - the true zero-silicone soft part
- Anti-colic valve is molded into the nipple, so no separate plastic vent inserts
- Borosilicate glass body; biodegradable rubber and FSC packaging
- The strictest option here for parents avoiding BOTH plastic and silicone in the nipple
Cons
- Screw ring (collar) and dust cap are polypropylene, and the ring is in the milk path
- Natural rubber ages and needs replacing more often than silicone; latex-allergy risk
- Rubber can impart a slight taste when new
- Not fully plastic-free as sold because of the PP ring
Notes
- Versions: standard-neck 4oz/8oz, wide-neck 5oz/8.5oz; wide-neck sleeved model adds a silicone sleeve
- A steel or natural-rubber replacement ring would push this to plastic-free; none is offered by the brand
