      Great socks - 2/14/2015

      Very comfortable and durable socks. Toe and heel areas solidly reinforced for wear and also provide additional cushioning. The socks stay up around the ankle and lower leg -- you're not constantly having to reach down to tug them up again. Colors are fast and show no fading after laundering. Great value!

      Great Socks! - 2/12/2015
      By: from New York City

      These socks have quickly become my favorites. They're warm, comfortable, attractive, and hopefully as durable as their name suggests. They fit wonderfully and stay in place all day. And, as noted by other reviewers, they are appropriate for a variety of dress styles and uses. I couldn't be more pleased.

      These socks are the best ever! The socks keep your feet warm and cushioned in the many extreme temperatures that you face in the winter and I would recommend these socks to everyone that want to have comfortable warm feet.

      1st review I ever made - 1/29/2015
      By: from Northampton Pa.

      I have never written a review about anything I had purchased on line and I buy a lot let alone a review on socks.I had read a lot of reviews about these socks so bought 6 pair. I bug my wife to do the laundry more cause after 6 days I want my Extra Socks.In the process of ordering more the only question I have is if they will be to hot in the summer while gardening or yard work.I 'm going to try some of the cotton version of same socks. I LOVE them.

      I had been a fan of Smartwool, until I tried these socks. I like the added wool in the heel and toe, and I like the height, as these socks stay in place all day and are long enough even when seated. Very comfortable and quality built. Well made wool socks may cost a little more than other materials, but wool works for all seasons.

      Still good, used to be better - 1/19/2015
      By: from NJ

      A year ago, I bought my first set of these socks. Since I had been very pleased with my purchase, I bought a second set this winter. These are still good socks. They are well made, comfortable to wear, and appear to be strong. But these are not as good as my last set. After the wash, they lost some shape and even seem to have shrunk a little.

    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.
