S'well is an eco-friendly lifestyle brand founded in 2010 in New York that creates reusable stainless steel bottles and other containers to reduce single-use plastic. Their fashionable, triple-layered, BPA-free bottles are vacuum-insulated to keep drinks cold for 36 hours and hot for 18 hours. As a partner of UNICEF, they have donated $1.4 million to provide clean water to vulnerable communities.
