Multi-beverage utility
These flasks are suitable for water, tea, or coffee. The stainless steel interior does not retain flavors between uses.
Portable travel design
The penguin-inspired shape is optimized for handheld use. It fits easily into small bags or side pockets for transit.
Thermal performance
The vacuum insulation maintains the temperature of hot tea or cold water. It prevents the exterior from becoming too hot or cold to hold.
