Designing for sustainability often begins with rethinking convenience, and Vapur, Inc. embodies this approach. Founded in 2009 to combat the 38 billion single-use plastic bottles discarded annually in the U.S., Vapur introduced the Anti-Bottle®—a foldable, collapsible, and reusable water bottle that redefined portable hydration. By addressing the inconvenience of rigid bottles, the Anti-Bottle gained global acclaim for its eco-friendly design and efficiency in manufacturing and transport. Building on this success, Vapur launched the Element, a groundbreaking innovation tailored for athletes and adventurers. Made in the USA, BPA-free, and 87% lighter than traditional bottles, the Element combines durability with versatility, featuring a patented carabiner-style top and compact foldability. Available at major retailers like REI and Target, it set a new standard for sustainable hydration on the go.
