Ornot's newest Habanero Delta Jersey tackles the warmer temperatures with lightweight Polartec Delta fabric technology. This tech works with your body's natural sweat production to keep you comfortable. Of course, sweat is the body's cooling system. And this new fabric uses a combination of hydrophobic and hydrophilic yarns that wicks and spreads perspiration across your body, rather than letting it pool against your skin.
It's one fundamental problem with modern AC: It's least reliable when demand is highest. Surging power use from air conditioners also adds to emissions, and climate change leads to more heat waves that lead to more AC use, in an escalating feedback loop. Some startups are trying to shrink the power use and carbon footprint of modern air-conditioning. But others are using ancient cooling techniques as inspiration. In India, some architects are turning to a material that's been used for cooling for thousands of years: terra-cotta.
