Hydration bottle from Iron Flask’s vacuum insulated stainless steel range, aimed at the same crowd as Hydro Flask style flasks but usually with more lid options in the box. At 950ml (32oz) it suits gym sessions, commuting, or keeping a day’s water on your desk, and the double wall build helps stop condensation soaking your bag.

Who is this bottle for?

If you like your water staying cold for hours, or you want a flask that will not leave sweaty rings on tables, this is the main draw. Vacuum insulation is also useful for hot drinks, though a wide bottle like this is more about water and sports drinks than coffee on the go.

  • 950ml capacity, fewer refills during the day, but it is bulkier in smaller cup holders.

  • Double wall insulation, helps keep drinks cold for longer and reduces exterior condensation.

  • Three lid styles, lets you choose between quick sips, a straw style, or a more secure carry option depending on how you use it.
