Pigeon
Pigeon's reputation rests on its silicone nipple, which parents widely rate as one of the closest to breastfeeding. The bottle body varies by line: the glass SofTouch pairs a borosilicate glass body with the silicone nipple, while the best-selling versions are PPSU or PP plastic. The nipple ring is plastic even on the glass bottle, so the glass SofTouch is minimal-contact rather than plastic-free - bought for the nipple more than for being a low-plastic vessel.
How clear are their specs?
Pigeon names the material of each bottle line (glass, PPSU, PP, T-Ester) and states the nipple is silicone, but the nipple-ring/collar material isn't called out prominently and reads as plastic on the glass bottle.
