ZOJIRUSHI SV-GEE50XA Stainless Steel Tuff Slim Vacuum Bottle

Greath thermos - the push button lid is very convenient. No leaking

I fill it up with hot tea first thing in the morning before work and it keeps my tea hot all through the work day, at least eight hours. It doesn't leak and is incredibly durable
