Altera Alpaca Performance Socks Adventure Medium Weight 12" OTC Sock (Brown Tweed) #20207017

The Altera Alpaca Adventure 12" OTC Heavy Weight Sock is our heaviest sock. It is lined with natural alpaca for comfort and performance. This sock has a dense terry loop construction throughout the entire sock for cushion, a reinforced heel and toe for durability and built-in arch support for a great fit. We have made recent improvements in durability and warmth. This field sock is the perfect choice for everything from barn chores, winter sports like ice fishing and skiing or just playing in the snow.


  • Moisture Wicking: Alpaca's hollow core fiber wicks moisture away from feet offering supreme comfort.
  • Thermal Regulation: Alpaca's superior hollow core fiber insulation is warm in cool weather and cool in warmer weather. This helps regulate body temperature regardless of the weather conditions, even when wet.
  • Silver Infusion Technology: Alpaca fiber is blended with yarn infused with precious metals for naturally odor free and antimicrobial comfort
  • Hypoallergenic: Alpaca fiber is free of lanolin, which people can be allergic to, and can be processed without the need for high temperatures or harsh chemicals in washing.
  • Soft: Alpaca fiber is naturally soft to the touch because it is several microns smaller in diameter than wool, giving its silky characteristic.
  • Flame Resistant: Alpaca fiber is flame resistant, meeting the standards of the US Consumer Product Safety Commission's rigid testing specifications as a Class-1 fiber for use in clothing.
