      Best Darn Socks Ever - 8/27/2015
      By: from Des Moines, Iowa

      I purchased these socks for the first time around 13 years ago and still wear several pairs from my original purchase. There was a period 6-7 years ago that the quality of these socks was below standard. My latest purchase indicates that Orvis has gone back their original standards as I can see that the material and feel is the same as the sock that I bought 13 years ago. You wont be disappointed.

      Can't Do Without - 8/13/2015

      I first purchased Orvis Invincible Extra socks two years ago and fell in love with them for comfort and durability. Now that I'm on a two year fly-fishing trip across the US I didn't have to think twice about the socks I wanted with me!

      I was curious as to the quality of the socks and have been very pleased with the fit and comfort and will order additional socks in the future.

      I've worn no others for many years - 7/19/2015
      By: from New York, NY

      I've worn no other socks than these for about 10 years -- winter, summer, any season. They're always comfortable -- warm in winter, and, surprisingly, cool in summer -- and my feet always stay dry, never sweaty. And they wear very, very well

      Great socks! - 6/24/2015
      By: from Virginia

      I purchased these socks and wondered why I paid so much for something i could buy locally for so much less. When I wore them for the first time i threw away all my other socks and will only wear these from now on!

      Really good! - 6/9/2015

      Merino wool is one of the best ingredients in any clothing product. I have experienced it before in 'vests' but not in socks. I am very happy with this Orvis product. The socks are comfortable, especially as there are pressure-points that have been reinforced appropriately, to cope with the relevant foot impacts. The socks also 'breath' well; something that is not often present in what other manufacturers provide. I recommend this product without hesitation.

      Great Socks - 6/3/2015
      By: from Scottsdale, AZ

      While these socks are a little pricey they last for just about forever, so in my book well worth the cost.

      Best socks ever - 6/2/2015
      By: from Ipswich, MA

      Friend recommended these and I bought them. Awesome socks that I can tell will last a long time. Thick where they should be and still fit in a loafer no problem. And don't worry about the green color option being too light. That's just the picture online. Mine are the right shade of green (a little darker).
