How does this compare to LifeFactory?

LifeFactory uses borosilicate glass with a protective silicone sleeve and a more boutique production model. Avent uses tempered glass without a sleeve and is far more widely distributed. Both are good options; we recommend choosing based on availability and accessory ecosystem.

Is the nipple plastic?

No. The nipple is medical-grade silicone. The cap and collar that hold the nipple in place are polypropylene.

Is it compatible with my Avent pump?

Yes, the glass bottles use the same standard Avent threading as the plastic line and work with the same pump and sterilizer accessories.

Our Editorial Standard

We assess materials, ingredient transparency, long-term durability, everyday practicality, replacement availability, manufacturer consistency, and overall value before including any recommendation. We only feature products we would calmly recommend to our own families.

Editorial

Why we recommend it

Tempered-glass body replaces the polypropylene used in the brand's plastic line while keeping the same trusted nipple shape and accessory ecosystem.
Compatible with the Avent breast pump, sterilizer, and storage system many families already own — a low-friction way to move a household away from plastic bottles.
Sold widely enough that replacement nipples, caps, and parts are easy to source for years, not months.
Stable, conservative design that has remained largely unchanged across multiple product generations.
