Plastic collectors collect plastic before it enters the ocean. Ocean-bound plastic is collected, upcycled or sustainably processed into new products As of March 16, 2023, 2023, 9,199,464 kg Ocean Bound plastic were collected Meet the collectors We work with people around the world where plastic pollution is at its worst to stop the flow at its source. Collectors trade plastic for money and gain access to social resources such as healthcare, education, mental health and financial security. To learn more about the plastic crisis of the ocean and how we play our part in solving. We are a group of people from different backgrounds and places in the world who love the ocean and share a common goal to preserve it. Creating a product that is partially made of stainless steel and partially recycled plastic that also feels and looks good is no easy task. However, we can now say with confidence that we have created the most sustainable reusable bottle. ## Features - AWARD-WINNING & MAKING REAL IMPACT – Loved by thousands and voted The Telegraph’s Best Reusable Coffee Cup 2024.

It will keep a drink hot for 4-6 hours, a quarter turn opens the valve at the top, lip runs all the way round so drink from any angle - ideal for having a hot drink while driving. And it doesn’t leak AT ALL, which means you can throw it on the passenger seat between slurps. The top part separates completely and it’s stainless steel inside, so it’s easy to keep clean. In short, it does everything you need it to and looks good. A bit pricey, but it’s probably going to be a lifetime purchase. I wouldn’t be without mine. ### ⭐⭐⭐⭐⭐ Just buy this, it’s perfect. *by on Reviewed in the United Kingdom 29 August 2026* It doesn’t leak and it keeps my mug of coffee piping hot for hours. If I fancy something cool instead, this cute flask will keep my drink icy cold all day. Perfect. ### ⭐⭐⭐⭐⭐ Yeti & Thermos are no match! *by on Reviewed in the United Kingdom 17 July 2025* Moved over Thermos Stainless King & Yeti Rambler. This Ocean Bottle Drinking vessel is better than both. I know because my wife & I have had both and returned both.Ocean Bottle keeps drinks hot for 6 hours. I know because we've tested.The drinking from these Ocean cups is easy and clean. No mess, just good, easy supping.The turn tops to lock keep drinks inside with no drips or leaks. And the tops come apart in two bits for deeper cleaning.These aren't as rugged as the Yeti Rambler but they are far superior in terms of retaining heat and for overall usage. The yeti kept our coffees hot for 2 hours tops. The Thermos was better at around 4 hours but drinking from them was awful and awkward.I'm not sure what the low rating reviewers are on with their poor reviews of these Ocean Bottle vessels. They are superb, worth the money and possibly the best travel cups for coffee on the market. ## Frequently Bought Together - Ocean Bottle Sky Blue - 350ml Brew Flask - Joseph Joseph 85025 Edge Dish Brush Green, 24 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/535761847-ocean-bottle-brew-flask-350ml-insulated-travel-flask-for-hot](https://www.desertcart.jp/products/535761847-ocean-bottle-brew-flask-350ml-insulated-travel-flask-for-hot) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-22*
