The thick stainless steel body can't be squeezed, so Bivo has designed a neat gravity-fed system with an impressively high flow rate. As water pours out of the nozzle, air enters back into the bottle through the straw.

While the bottle is made in China, Bivo professes to use “factories and vendors we trust and that care for their employees.” Additionally, Bivo is offsetting its carbon emissions by investing in the Cleaner, Safer Water in Cambodia project in order to make the One bottle a carbon-neutral product.
