This is by far the nicest drink-ware we have ever done! It's is so well made you will love it and have it for a very long time! This is a high quality item with workmanship you can see/feel.

Size: 20.9oz - double wall 18/8 stainless steel thermal bottle with copper vacuum insulation, threaded one-touch push-button lid with locking mechanism, and carrying handle. 

Superior Insulation: The copper plating on the inner wall is an extra line of defence 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. 

This water bottle is made from double-walled, stainless steel.

Bottles feature a copper vacuum insulation that keeps drinks hot  for 12 hours or cold for 24 hours.

The dual-walled construction prevents condensation from forming on the outside of the bottle.

Features a screw-on, push-button lid with a locking mechanism and carrying handle.
