As you can imagine, many of the materials in your clothes and other everyday products are not natural, they aren't made in the USA, and they don't perform when you need them most. Over time, that gets expensive… and unsustainable. 

Altera started in 2013 to provide a sustainable solution. Lots of trial and error resulted in the development of alpaca socks that perform consistently in variable conditions, provide moisture wicking, regulate based on warm and cold temperatures, offer antimicrobial protection, hypoallergenic relief, and are durable and washer/dryer safe.

With our unconditional lifetime warranty, we look forward to seeing you wear the last pair of socks you will ever need to buy.
