Cashmere for summer? Yes, the ultra soft material isn't just great for winter, Naadam has crafted a cotton and cashmere blend called Nanoweight that rivals traditional 100% cotton with a material that gets softer and is dramatically lighter. It gets softer the more you wear it and wash it and while it delivers a nice elasticity, it's also much more resistant to stretch than cotton. Nanoweight is currently available in a line of tees, polos, and lightweight sweaters.
