Nanobébé Flexy is a soft silicone bottle for parents who like the feel of Comotomo but want a verified US price. Nanobébé says the bottle is made from 100% medical-grade silicone, free from BPA, PVC and phthalates, and soft enough to feel natural while staying durable and easy for small hands to hold. It comes in 5 oz and 9 oz sizes, sold in 2-packs: $17.99 for the 5 oz pack and $18.99 for the 9 oz pack when we checked, both shown as sale prices. That is about $9.00 per 5 oz bottle, more than the plastic vented bottles here. The weakness is documentation. Nanobébé's product page answers yes to whether the bottle helps reduce colic but does not describe a vent design or cite a study, and it lists fewer specs than any other bottle on this list. That is why it ranks last despite a fair price. We compared documented features and published prices.
