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 is entirely carbon neutral and 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.
