In the middle of a harsh Indian summer, when temperatures climb past 45°C and access to cool drinking water becomes more necessity than comfort, a simple cloth bag is quietly drawing attention online for doing what most people now rely on refrigerators for.
Priced at around Rs 300, the portable cooling bag works without electricity, batteries, or any modern machinery. All it needs is air, water, and time.
How this works
Its principle is remarkably simple. The bag is made using a porous fabric that retains moisture. When water is poured over it, the outer surface stays damp. As that water slowly evaporates, it pulls heat away from the contents inside, naturally lowering the temperature. The result is cool drinking water, even under intense summer heat.
Entrepreneur Digambar Gaikwad is helping revive one of these forgotten methods through his company, Bharat Agro.
The idea may feel innovative to younger audiences discovering it through viral videos, but in reality, it is far from new. For generations, Indian households relied on similar evaporative cooling methods through clay pots, earthen matkas, and damp cloth storage systems to keep water cool during the summer months.
These traditional systems worked with the climate rather than against it, using natural airflow and evaporation instead of electricity. But as refrigerators became more common and aspirational, many such practices slowly disappeared from everyday life.
Now, entrepreneur Digambar Gaikwad is helping revive one of these forgotten methods through his company, Bharat Agro. By redesigning the concept into a lightweight, portable hanging bag, he has made the traditional cooling system easier to use in modern settings.
The bag can be hung on a balcony, a hook outside the house, a tree branch, or even near a farm shelter. It requires little maintenance and is particularly useful for those who spend long hours outdoors — farmers working in the fields, labourers under the sun, delivery workers, and long-distance travellers who often struggle to access cold drinking water during the day.
In many parts of India, extreme heat is no longer just seasonal discomfort but a growing public health concern. Heatwaves regularly lead to dehydration, exhaustion, and even fatalities, particularly among outdoor workers and vulnerable communities.
In that context, affordable access to cool water is not a luxury but a basic need.
What makes this small cloth bag significant is not just its price, but what it represents — a reminder that solutions to modern problems do not always require expensive technology. Sometimes, they already exist in practices we left behind.
For Rs 300, this is less a product and more a return to common sense.
