The Trekka Tanka holds 1 litre (4 standard size glasses), it provides a little more volume than a regular bottle, but without the extra bulk.

• Care Instructions:
  ECOtankas are very easy to care for, simply wash and rinse as you would your dishes, or place in the dishwasher. Alternatively, baking soda and warm water can be used to cleanse and freshen your bottle. They may be steralised with boiling water. Please do not place in the freezer.

• Summer Tip:
  For a drink that stays cool for hours in the summer, fill your bottle with ice cubes, top with water then fit a kooler cover. All ECOtanka bottles have a special wide mouth, allowing ice cubes to be used for an instant cold drink.

• 1 Year Warranty
  All ECOtankas are solid 304 high quality stainless steel food grade and have a 1 year warranty against faulty manufacturing.
