About Ocean Bottle
In 2018, Nick Doman and William Pearson established Ocean Bottle in London, England as a social impact brand to help tackle the oversaturation of mismanaged plastic waste worldwide. Since then, the award-winning brand has prevented the weight equivalent of over 1 billion plastic bottles from reaching our oceans. The bottles are designed in Norway and made in Shanghai with ocean-bound plastics coming from the Philippines and India. Beyond providing an impactful solution to plastic pollution with their reusables, the brand also developed Ocean Co, which is their commitment to restoring and protecting the ocean’s health. Today, Ocean Bottle and Ocean Co. work with collection organisations on the frontline of the ocean plastics crisis, such as Plastics for Change, Plastic Bank, and rePurpose Global. Together, these organisations collect 11.4kg of plastic waste per bottle sold.

Reviews & Testing From Our Team

Brew Flask - Sahara Red
My family and I have been testing this flask throughout our summer for post swim coffees on the beach (and beyond). The lid is a super innovative design - love how it stops coffee from spilling when knocked about a bit and I found it very easy to wash out quickly (we had numerous sand incidents at the beach so this was particularly helpful). I tested the flask in Sahara Red and so many people complimented the color and stylish design and showed interest in the whole Ocean Bottle mission. It also kept coffee and chai lattes hot for a couple of hours on the beach though I’m yet to test it for longer than that.

Ocean Bottle Original (Sand Stone) & OB Lite (Shale Green)
We’ve been using the Ocean Bottle Original for a couple of months for all kinds of things from sport to a day out and about. The bottle is a great size, fitting in a ton of liquid for the day and keeping the temperature nice and cool - which is quite the feat as we’ve used it on 39°C (~102°F) days a few times this summer. The OB Lite though is the real winner for us. Lyall and I have been both trying to assert our ownership over this little beauty. It’s stylish in such an understated way, holds just the right amount of water for our sporting activities (we do yoga, gym, running and jujitsu) and fits nicely into our car holder. Also our 3 year old son can easily carry it and drink from it independently which is harder with the big bottles. I also love that the OB Lite will be easier to recycle if it ever comes to the end of its life.
