This is a 26 oz double wall 18/8 stainless steel vacuum thermal bottle with a threaded insulated lid.
The stainless steel insulated lid, narrow opening, vacuum insulated body and copper plated inner wall help retain the internal temperature longer.
The copper plated inner wall can make a difference of 41° F/5° C over 24 hours and prevents heat from entering or exiting the bottle by thermal radiation.
HOT 8 hours. COLD 16 hours.
The durable brushed steel top and bottom protect the finish of your bottle from every day use.
Hand wash recommended.
