⚡ At a Glance
- • Temperature Retention: Vacuum insulation maintains beverage temperature for hours, with users reporting retention over multiple hours or even days
- • Best for: Commuters, hikers and anyone who needs a reliable flask for long outings
- • Not ideal for: Those needing a compact cup for single short journeys
Vacuum insulation combined with double-walled stainless steel keeps drinks hot or cold for extended periods. A twist-pour stopper and full-lid cup make pouring and sharing straightforward while preventing spills.
Long-lasting temperature control - thanks to vacuum insulation
Vacuum insulation uses a double-walled stainless steel construction with an airless gap between walls to limit heat transfer. That physical barrier slows both heat loss and heat gain.
Hot drinks stay warm and iced drinks remain chilly for many hours, so drinks can be enjoyed at the preferred temperature long after preparation.
Mess-free pouring and sharing - with a twist-pour stopper and built-in cup
A twist-and-pour stopper allows liquid to be dispensed without fully removing the lid, and a full-lid cup provides a ready receptacle for drinking or sharing. The stopper seals tightly to reduce leaks when closed.
Smooth, controlled pouring avoids splashes and means hot drinks can be served safely on the move, while the built-in cup removes the need to carry an extra mug.
Robust daily use - with stainless steel construction and leak-proof design
Stainless steel is used inside and out for impact resistance and corrosion protection, and design elements aim to prevent leaks during transit. Surfaces clean with warm soapy water as recommended.
Durable construction withstands knocks and regular handling, offering a long-lived flask suited to commuting, outdoor activity and everyday use.
