Lifefactory Glass Baby Bottle with Silicone Sleeve
Borosilicate glass with a grippy silicone sleeve - but the cap, ring, and stopper are polypropylene that touches the milk path.
The verdict: Minimal plastic contact
The bottle is borosilicate glass and the sleeve and nipple are silicone, but the cap, screw ring, and sealing stopper are polypropylene - and the ring plus the sippy/flat cap sit right in the milk path. So despite the "glass" branding, plastic does touch the drink. Better than an all-PP bottle, and the glass body avoids the worst microplastic shedding, but it's not silicone-only because of the PP collar and cap.
What it's made of
| Part | Material | Food contact |
|---|---|---|
| bottle body made in France | Borosilicate Glass | Yes primary |
| nipple silicone nipple (stage 1/2) | Silicone | Yes primary |
| screw ring / collar PP ring seats the nipple against the bottle - milk contacts the ring lip | Polypropylene PP, #5 | Yes seal |
| cap (flat cap or sippy cap) PP; the sippy-spout cap variant is the drink surface for toddlers | Polypropylene PP, #5 | Yes primary |
| stopper / sealing disc PP travel stopper that seals the bottle opening | Polypropylene PP, #5 | Yes seal |
| protective sleeve removable silicone sleeve for grip and drop protection | Silicone | No |
A widely available borosilicate glass baby bottle wrapped in a colorful silicone sleeve for grip and shatter resistance. Sold in 4oz, 8oz, and 9oz sizes, and it converts toward toddlerhood with an optional silicone-sleeved sippy cap - though the sippy spout itself is polypropylene, so a toddler drinks through plastic at that stage.
Pros
- Borosilicate glass body - no microplastic shedding from the bottle itself
- Silicone sleeve makes glass far more drop-tolerant and grippable
- Very widely available; converts to a sippy with an add-on cap
- See-through - easy to gauge how much milk is left
Cons
- The sippy-cap conversion drinks through plastic, not silicone
- Heavier than steel; still breakable if the sleeve is off
Notes
- Sizes: 4oz, 8oz, 9oz; optional sippy cap and flat cap sold for the same bottles
- To minimize plastic contact, some parents pair the glass bottle with a silicone nipple only and skip the sippy-cap stage
