Over the past few years, Hydro Flask has taken the world by storm with its pioneering insulation technology. Unlike a standard thermos, which only keeps liquids lukewarm at best, the Hydro Flask boasts the ability to keep liquids at a balmy 160 degrees for twelve hours. This has changed the name of the game when it comes to insulated water bottles, and a number of competitors have hit the market over the years.
One of the most popular competitors is Thermoflask. This design came second, and the engineers aim to take inspiration from the technology of the Hydro Flask while also improving upon it. Thermoflask is a cheaper alternative to Hydro Flask, but what does that mean? Does a Thermoflask water bottle actually stand up to Hydro Flask in terms of performance?
