Neoprene Thermal Bottle Sleeve
Thinkbaby
Thinkbaby's eco-friendly sleeves are made from Limestone. Provide maximum insulation and protection. They feel just like traditional neoprene, and will not only protect the bottles, but will also provide significant insulation. Made to fit tight, so they cannot be easily removed by a toddler. Hand wash. Recommend using a detergent that is free of chlorine.
