LIVING STORY · VOL.019
A bottle made for every day is about more than capacity—it is about rhythm. Estiva balances a practical 590ml volume with an easy-carry handle and an included tea infuser for cold-brewed tea or fruit-infused water. From drinking and cleaning to changing the silicone sleeve, each detail is designed to make hydration feel natural at work, on the move and outdoors.

One bottle structure, presented in 12 coordinated colorways. Charcoal・Midnight Black is shown first by default; choose your preferred bottle and silicone sleeve combination from the product options.

The 590ml capacity balances daily hydration with portability. A carry handle and removable silicone sleeve make it comfortable to take from commuting and work to exercise and weekends outdoors.


Estiva is designed to stay close through workdays, city walks and slower weekends. The following images feature the default Charcoal・Midnight Black colorway, showing how its understated finish fits naturally into different everyday settings.



The included infuser supports cold-brewed tea and fruit-infused water. The Tritan bottle material is rated from -20°C to 100°C, but the single-wall body may become hot; the recommended beverage temperature is 5°C–60°C.


The bottle, silicone sleeve, tea infuser, upper handle lid and lower stopper lid can be separated for cleaning. Use diluted neutral dishwashing liquid with a soft sponge or suitable bottle brush. Do not place in boiling water or use steam sterilization.

Complete everyday use with compatible replacement and cleaning accessories. A tea infuser is already included with every Estiva bottle; purchase another only when a replacement is needed.
