Altera Alpaca — Performance Redefined.

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

Our commitment doesn’t end with the sock. Every pair is backed by our Unconditional Lifetime Warranty—because performance should never be a question mark.
