Esbit 500mL Vacuum Flask

Enjoy easy pouring with the push button stopper on the 500mL Vacuum Flask from Esbit. Simply depress the button to dispense some liquid, and press again to stop the flow. The double-wall construction provides insulation that keeps the contents hot or cold for up to 12 hours so you can enjoy a refreshing drink all day. The lid functions as a mug, and also serves to secure a nesting cup so you can share with a friend. Both the stainless steel and plastics used to create this flask are BPA-free.
