Ocean Bottle Brew Flask 350ml | Insulated Travel Flask for Hot & Cold Drinks | Recycled Stainless Steel | Sustainable, Eco Friendly Gift (Obsidian Black)

Someone bought one of these for me and I love it, so I bought one for my wife. 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.

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.

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.

Great for coffee sipping, completely leak proof and stays hot for ages

Nice build quality and works well. Light colour shows up black coffee so I’d choose darker next time.

Excellent quality travel flask. It keeps drinks hot for hours without leaking, and the size is perfect for commuting. The finish feels premium and it’s nice knowing it’s made using recycled materials.

I came to use my brew flask at the weekend as I was going away, I realised that the top was crooked. As it cost a lot of money and with a 10 year guarantee you would expect better. New I should have purchased from manufacturer, it would have been less money too.

Keeps drinks hot for a good 6 hours (maybe longer, I've not tested) even when the outside of the bottle is really cold to the touch. It hasn't leaked at all, so perfect to put into my bag or lay down. Used everyday for coffee since my 1st purchase back in January (9months). The brew flask lid (the only lid i've tried) is good to drink from unlike many flask / reusable bottles. Dishwasher safe and hasn't faded in colour. Great fit for my cars cup holders.

En general estoy satisfecho sin embargo, tengo que decir que debido a su diseño puede a veces derramarse sino lo armas o ajustas correctamente.

Es perfecto

Love this bottle, but it stained from foods on plates when washed in the dishwasher which was really disappointing. Despite saying its dishwasher safe, I would avoid!

Great for hot and cold beverages. Keeps beverages hot and cold. Doesn’t leak in any position! Great purchase!!’

I’ve been using this flask at work every day and I’m impressed.
