One bottle, every Dhaka day

Reza is in his third year at NSU. He used to carry a steel water bottle that bashed against his books and dented the lid every other week.
The SmartPik collapsible silicone bottle clipped to his bag, folded flat at the bottom of his backpack between classes, and held 600ml of cold water in the Dhaka heat.
“I can fold it. I can clip it. It doesn’t sweat. I’m done with steel bottles.”
