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.
Trekka tankas fit all of the standard ECOtanka lid range and the trekka size KOOLER covers.
ECOtankas are very easy to care for, simply wash and rinse as you would your dishes. 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.
Stainless Steel brush finish bottles can be put in your dishwasher for easy cleaning. Painted bottles CAN NOT be put in a dishwasher.
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.
