17 oz. double wall 18/8 stainless steel thermal bottle with copper vacuum insulation and 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 41F/5C over 24 hours and prevents heat from entering or exiting the bottle by thermal radiation. The durable brushed steel top and bottom protect the finish of your bottle from everyday use.
