Review – Hydro Flask Insulated Coffee Flask with Flex Sip Lid

Hydro Flask Insulated Coffee with Flex Sip Lid How can you have great coffee on every ride? How can you reduce plastic waste? How can you conform to social distancing guidelines? One simple solution, is a quality insulated coffee flask…

The Hydro Flask Flex Stainless Steel Vacuum Insulated Coffee Flask is a superb example of a portable coffee solution; allowing you to take steaming hot coffee with you for those deep winter mid-ride breaks.

I have always been a great fan of #coffeeoutside—it just tastes better. There is nothing like the feeling of sipping on a mug full of freshly brewed coffee sat on the side of a mountain or sheltered from the wind in a forest.

Taking a hot drink with you on an outdoors adventure, particularly a bike ride, can be a little problematic though… you need a flask that is robust, leak-proof, and will keep your beverage warm for several hours.

After much searching and testing, I came across the Hydro Flask Flex. This insulated bottle, when combined with the new Sip Lid, makes for the perfect cycling coffee solution.

The Hydro Flask Flex is made with pro-grade stainless steel that is BPA and Phthalate Free—to ensure a pure taste and no flavour transfer. The high-grade metal is also incredibly robust and will stand up to the abuse of even the toughest adventures.

To keep you drink cool or hot, Hydro Flask use a unique TempShield technology. This double wall vacuum insulation protects from temperature changes for hours; hot drinks stay at a good temperature for up to six hours, from my experience.

I opted for the 16oz version of the Hydro Flask Flex, which equates to 473 ml in metric standards. That is similar to a large sized cup of coffee from most UK coffee shops.

The party trick of the Hydro Flask Flex is the new Sip Lid. This uses the same soft-touch feel and robust hanging loop as the standard Hydro Flask insulated lid; but it allows you to sip from the container through a small spout opening, rather than needing to remove the complete lid unit; ideal for keeping the contents hotter for longer.

The Hydro Flask Flex will just fit in a bicycle bottle cage—a defining demand from my side. You need to use an old-style metal bottle cage and slightly bend it out; I then fitted some offcuts of bar tape to the contact points with the cage to save the paintwork on the bottle. Alternatively, you could use a rack-top bag or an adjustable cage such as the Arundel Looney Bin.

Overall, this is a great insulated coffee flask. It has allowed me to take a warming brew up onto the hills on many occasions; supplying a portable and perfect coffee every time. Quality kit from Hydro Flask.
