Cusa Retro Thermos


The perfect companion to your Cusa Tea or Cusa Coffee!

Our 20oz double-walled vacuum insulated Retros Thermos will keep your tea or coffee hot or cold for hours. It can be used at home, work, at the beach or at the campsite - just about anywhere!

No cup? No problem - this thermos includes one. Just detach and pour yourself a cup or just a few sips. It's ideal for keeping your beverage hot or iced, and pouring just a bit at a time so your entire drink doesn't reach room temp before you're done with it.

Retro Thermos Features:

  • Detachable cup for sipping on-the-go
  • 20oz size to keep you going
  • Double-wall stainless steel for 8+ hours of insulation
  • Push button open/close keeps it leakproof
  • Durable powder coating that can stand up to life's adventures
  • Super sweet Cusa logo!

    Meet our Founder, Jim Lamancusa.

    At Cusa Tea, our mission is to recreate the taste and experience of tea that inspired me over 15 years ago. With a complete education in the craft and culture of tea and exploration of plantations and sops throughout China and India, I was inspired to create a premium and functional tea you can drink conveniently at home, in the office or on-the-go, for overall wellness. With the convenience of instant tea and the full flavor, aroma and antioxidants of traditional tea, your favorite flavors are now available in seconds.
