Our logo on a 20oz double wall 18/8 stainless steel thermal tumbler with copper vacuum insulation, threaded snap-fit lid, and powder coated finish.

The copper plating on the inner wall is an extra defense against temperature transfer. Heat escapes much slower so your hot coffee stays hot even in a snow storm, and heat enters much slower so your ice water doesn't melt even under a blistering summer sun.

We have tested this bottle with 160° water placed on it's side for 7 hours mimicking being in a saddle bag with coffee from the morning campsite. The bottle did not leak when the lid was properly secured and the water only dropped to 113° at the end of our test.

Pair it with the OBR bottle wrap for even better value and have a holder on your luggage for your new bottle for ease of access and security.
