We partnered with Miir for these amazing insulated travel thermoses. They keep cold drinks ice cold, and hot drinks really hot. Not only do they make the best products around, they do so much work with non profits. MiiR partners with some of the most respected nonprofits in the world to create sustainable giving projects supporting clean water, a healthy environment and strong communities. The company has given over $1,000,000 and empowered the lives of 115,000+ people worldwide, and its customers are invited to experience the story behind their purchase by registering the Give Code™ found on the base of their MiiR product.
