When it comes to packing, I am always on the lookout for light weight products that would work for me. Rite Aid sells Phillip Edwards socks for only 99 cents. These socks are made of 97% polyester and 3% spandex. They are light, thin, and come plain or whimsical in design. Because of the cost, I don"t expect them to last a long time, but they are perfect for packing and I love them. For more pack light ideas check out www.mimipackslight.com
