The compact Hydro Flask Micro Hydro 400ml thermos flask is the perfect balance between minimalist style and superior thermal performance. It is designed for anyone who wants to have their favorite hot tea, coffee or refreshing cold water always at hand without the burden of a large and heavy package. Thanks to its slim design with a diameter of 6.48 cm and a height of 22.1 cm, the thermos fits comfortably in the palm of your hand, school and work bags and most standard car cup holders. With an extremely low weight of only 222 g , you will hardly notice it in your luggage, and the included innovative detachable FlexClip™ strap allows you to quickly attach it to the loops of a backpack or belt.

Inside, advanced double-walled TempShield® vacuum insulation keeps liquids ice cold for up to 24 hours or warm for up to 10 hours, while preventing condensation from forming on the exterior walls. The body of the thermos is made of 100% 18/8 stainless steel , which does not change the taste of drinks or absorb unpleasant odors. The exterior is decorated with a non-slip Color Last™ powder coating, which is resistant to scratches and impacts. The lid reliably seals and prevents any spillage while moving.
