The Ocean Bottle GO 500 ml bottle has vacuum insulation to keep drinks cold for up to eighteen hours, and is designed with a dual opening function, making it perfect for on-the-go. The bottle has a leak-proof lid and provides easy access for filling, cleaning, and adding ice. The GO bottle takes all the best features of the original Ocean Bottle but has a more sporty design allowing you to drink using only one hand. Each Ocean Bottle collects 1,000 plastic bottles to improve livelihoods in coastal communities. The bottle is made from 90% recycled stainless steel and other recycled materials. Due to the silicone straw the GO bottle can only be used for cold drinks. Presented in a responsibly sourced recycled cardboard gift box.
