ThinkSport 750ml double walled vacuum insulated stainless water bottle, keeps liquids hot or cold for hours.

The Thinksport 750ml is a super light weight stainless steel double walled bottle. The vacuum insulated area between these sealed walls creates an extremely effective thermal insulation layer, that keeps beverage hot or cold for hours.  Also because it is thermally insulated you will not feel the hot or cold from inside the bottle, so it will also prevent the condensation commonly seen on single walled botlles. It is free of Bisphenol-A, PVC, cadmium, lead, other biologically toxic chemicals.


  • Holds 25oz (750ml) 
  • Weighs less than 14 ounces (empty)
  • Removable easy to drink from spout. 
  • Removable metal filter helps keep ice or tea leaves out while drinking
  • Removing spout and filter reveals wide mouth for easy filling of ice or liquids.
  • Double walled, vacuum sealed stainless steel bottle keeps contents hot or cold for hours**
  • Vacuum reduces the ability for hot beverages to radiate to the exterior surface of the bottle and reduces the chance of any bottle "sweating"

**For safety purposes: Assume that the hot temperatures of  liquid put into the bottle when filling, will still be that hot hours later.
