#1. In summer, linen is not simply a beautiful and useful fabric for the home. Clothing made from linen is known for its remarkable protection from the heat. In hot weather, those wearing linen have been found to have a skin surface temperature approximately 4 degrees lower than those wearing cotton, and an even larger degree drop from those wearing synthetic fibers. Linen is extremely breathable, easily allowing heat to escape. Linen can also absorb and retain up to 20% of its own weight in moisture, without feeling clammy or even appearing to be wet. All fabrics offer some UV-protection, but linen provides the most out of all non-synthetics. Naturally, its fiber structure and weave pattern make it slightly reflective.
