Stay cool in warm weather with fabrics that are light in weight.
Medium weights are best in spring and of course the warmer it gets the lighter you will want your fabric to be. Choose breathable fabrics such as silk, cotton, linen, muslin, gauze, etc. Some of the man-made materials are great for the hot weather and are great for laundering. Choose rayon, polyester, or blends.
They are not always less expensive, yet they wear well and many times look as good as the natural fibers. For sportswear the best choice is a man-made fabric with wicking capabilities that pull moisture to the surface where it is immediately evaporated, keeping you dry, comfortable and fresh looking.
