How this score breaks down
Strengths
- Borosilicate glass body with silicone nipple, collar, cap, and sleeve, no plastic touch points
- Brand states it is free of BPA, BPS, phthalates, PFAS, and lead
- Grows into a sip cup or dispenser with separate Companion Tops
- Lifetime warranty
Trade-offs
- Food-grade silicone is a synthetic polymer: not a petroleum plastic, but fossil-fuel made, not recyclable, and able to release trace siloxanes or particles under high heat or repeated sterilization
- Companion Tops and the chiller are sold separately
- No third-party non-toxic certification confirmed from a primary source
