An ancient and universal fiber

One of the oldest and most universal fibers, felted or woven wool has been used for garments and household linens since the earliest civilizations. Wool textiles have been documented as far back as 3,000 B.C.

The superior quality of wool from merino sheep

Thousands of years of evolution and selective breeding have resulted in merino sheep capable of producing a super-fine wool fiber. One square inch of merino fleece produces nearly four times as many wool fibers as other breeds of sheep. Interlaced with millions of microscopic air pockets, which act as Nature’s most effective insulator, merino fibers naturally reduce the passage of heat by trapping air between the woolen fibers. Because merino fibers are smaller in diameter and more abundant than in any other wool, they trap more air and keep the wearer naturally more comfortable.

Versatile, durable and comfortable

Merino wool keeps the wearer warm in cold weather and cool in hot weather. These remarkable fibers also absorb up to 30% of their own weight in moisture, pulling vapor away from the body so that the wearer stays dry and comfortable regardless of the temperature.

Fine merino wool is soft, not scratchy!

Modern technology has made it possible to sort and select only the finest merino fibers. Merino wool has a microscopic diameter—about one-third to one-tenth the thickness of a human hair. The smaller the diameter, the finer, softer, and less scratchy the fabric will be. Lustrous merino wool produces fabric that can be worn next to the skin without discomfort, is soft, and always provides an exceptional hand and distinctive style. Orvis offers a wide range of luxuriously soft merino wool clothing for men.
