While the race to create the most versatile fabric has yielded significant offerings from the likes of The North Face and Columbia, a pair of researchers at the University of Maryland may have made the next promising push. Their fabric is made from two yarns—one to absorb water and one to repel it. Together, they react to moisture from your body. When you sweat, the fabric opens little holes to allow heat to escape. When you’re cold, the fabric expands and traps heat in. Though no clothing manufacturers have access to the innovation just yet, the pair don’t see gear as the end goal—the fabric could greatly reduce home energy costs, too. Read more at Gizmodo.
