Hydro Flask 21oz Standard Mouth Bottle Olive Information

Season : 2021W R

Brand : Hydro Flask

Code : S21SX306

If you've never heard of Hydro Flask before then I'll fill you in; founded in 2009 and based in Bend in Oregon, Hydro Flask are a great group of individuals with a passion and love for the outdoors. Since their launch, Hydro Flask has gone from strength to strength hitting 1 million sales in 2011, then branching into Europe in 2015 and then expanding worldwide by the end of 2016. Through their Parks for All scheme, Hydro Flask provides grants to non-profit organisations focused on building, maintaining, restoring or providing better access to parks all over the world.

So let's start with the insulation. Hydro Flask uses TempShield, a double wall, vacuum insulated technology that guards the temperature of any drink, meaning cold stays cold for up to 24 hours and hot stays steaming hot for up to 12 hours. TempShield also guarantees no condensation or heat transfer to the outside of the bottle.

All of Hydro Flasks products are made with 18/8 pro-grade stainless steel which works wonders for taste. This top quality stainless steel protects against any flavour transfer which means that after a quick rinse you can use the same flask for multiple different drinks throughout the day and it won't taste like stale coffee. It is super easy to clean (yes, even if you accidentally leave it half-full of coffee in your car over a hot weekend) and is also BPA-Free and Phthalate-Free.

The slip-free proprietary powder coating makes your bottle much easier to carry and keeps your bottle slip free. The bottle comes with a fully insulated flex cap but also works exceptionally well with Hydro Flasks insulated Sport Cap. 

And if you need any more convincing (although I'm not sure you do), Hydro Flask comes with an easy, hassle-free lifetime warranty, meaning you get peace of mind and can enjoy your flask for years and years.
