why stainless steel

insular leak free bottles 

Our bottles are completely unique. We have toiled long and hard to develop a cap that won’t leak without using straws or sippers and a bottle that won’t get slippery with condensation. The double walled design not only makes these bottles sturdy and durable, but also insulates the liquid so cold drinks stay cold and hot drinks stay hot, just they way you want them!
 
 
 Constructed out of 18/8 stainless steel, these bottles are built to last and last and will not leach harmful toxins like plastic bottles and are far more durable than aluminium alternatives.
 
 
Cocoons come in a huge range of sizes, colours and themes to suit all ages.
