Many lightweight woolen fabrics are good for year-around use. Other versatile wool fabrics are comfortable on the hottest days of summer or the coldest times of winter. Wool feels soft and luxurious, is resilient with natural elasticity and it resists wrinkles. Crush, stretch or twist wool and it springs back into shape. Wool garments don't bag or sag and they are durable.
Wool wears for years with lasting good looks.
Wool is a good investment. Some do, some don't. Woolen fabrics that have not been treated for washability will shrink because wool has a central hollow core made up of overlaps like shingles on a roof or scales on a fish. Agitate these untreated fibers in soap and hot water and they interlock so that each fiber can't spring back to its original length, thus the fabric shrinks. Chemists have developed a mild, thin resin which is spread evenly over the fiber surface before spinning.
