Our baby bottles are made of the highest quality, thermal shock resistant borosilicate glass. This allows our bottles to transition safely from freezer to boiling water. The silicone sleeves provide a good gripping surface for little hands and help protect against the occasional drop. - Protective medical-grade silicone sleeve provides a tactile non-slip gripping surface and helps prevent breakage - While very durable, our bottles are still glass and are not unbreakable - Dishwasher safe (place cap parts and nipple on top rack/no need to remove silicone sleeve unless desired) - As baby grows we offer a range of caps (sippy and flat) to extend the life of your bottle - Includes polypropylene (PP#5) cap, ring and stopper.

In creating a sleeve for Thinkbaby bottles, we looked carefully at the solutions on the market. We wanted a material that would provide maximum insulation and protection.

Our investigation took us to our friends at Patagonia. Patagonia largely pioneered the use of Limestone based neoprene to replace traditional neoprene for their wetsuits.

Thinkbaby's sleeves are made from Limestone. They feel just like traditional neoprene.
