Altera Alpaca

Description:

At Altera, we believe your gear should work as hard as you do. Thats why weve redefined performance from the ground upstarting with socks. Using the natural power of alpaca fiber, weve created socks that outperform cotton and synthetics in comfort, durability, moisture control, and temperature regulation.

Our commitment doesnt end with the sock. Every pair is backed by our Unconditional Lifetime Warrantybecause performance should never be a question mark.
