A good water bottle is a key component to staying hydrated. Nobody really wants leaching plastic, leaky lids or even worse, disposable plastic single-use bottles. Hydro Flask make a range of premium water bottles that have a vacuum flask built in that promises to keep ice cubes and chilled water for 24 hours and hot liquids for 6. My first impression of the 32oz wide mouth flask in Mint colour I received was it’s high build quality and grippy exterior. It passed the first test with flying colours – water tasted like pure, fresh and clean, no metallic aftertaste, which is common in cheaper metal bodied bottles.

I have used to exclusively for the last three weeks and it’s made a great impression – it’s sturdy, leak proof, stylish and delivers cool, fresh water whether thrown in a bag, left in the car or sitting on my desk.

About Hydro-Flask

Hydro Flask (the company) was founded in 2009 in Oregon and specialised from the start in insulated drinks bottles. They hit a million sales a year by 2011 and expanded to have a range that covers beer, coffee, water and food – all insulated. They’ve won numerous staffing awards in the US and are expanding from their US home market to go worldwide.


The Hydro flasks share a common design language. The same cylinder – in different colours and sizes – curves inwards near the top to fit a large lids. They’re metal bodied and covered with a grippy sprayed on surface that makes it much harder to drop and isn’t slippy when wet.  Internally every Hydro Flask is a vacuum flask. I actually found their 24 hour limit pessimistic, but I have to admit my cold testing was done in February indoor temperatures rather than in the middle of summer.

The lids are removable and the default is a ‘Flex Cap’. This is a solid plastic cap with a flexible handle held on with metal rivets. Hydro Flask have a range of replacement tops that include one with a straw lid and one with a flip lid as well as replacement flex caps. It’s available in a range of sizes and colours, including a personal customization option.

The Hydro Flask range starts at around £20 for the smallest bottle and increases to around £60 for the largest. The replacement lids are £5 – 10 depending on type. My mid-size 32oz bottle costs around £40 and for a premium product like this, that’s a good price particularly as it comes with a lifetime warranty against manufacturer defects, including loss of insulation.

Ever forgot your water bottle in the sun or in the car and returned thirsty to a lukewarm tepid serving? The biggest appeal of the Hydro Flask range is its promise to keep your water at the temperature you want it. We accidentally left it near a hot radiator for a few hours and the water from the flask was still chilled when we opened it. (Not recommended!)

As an everyday carry the Hydro Flask is obviously heavier than plastic alternatives – so it’s a trade off for someone who cares about weight. I don’t, but my wife does. Even if its too heavy for your taste as a regular bottle for your regular bag, it’s still a fantastic purchase if you BBQ, camp or picnic in the summer months. Get a nice big one, fill it up and everyone gets a cold drink at the hottest part of the day. Add to that the selection of colours and lids, it’s toughness and finish it off with a lifetime warranty and it’s a great buy. Highly recommended.
