Product Description

WHETHER YOU ARE WITHIN SIGHT of the peak in frigid conditions or out for a weekend hike in July, Altera has your back - or rather your feet. Introducing the PREVAIL sock from Altera.

ALTERA High Performance Alpaca Fiber Technology (HPAFT) has provided the basis for the first significant improvement in base layer performance in two decades. The legendary softness and unique thermal and comfort properties of the alpaca fiber make the rarity and time intensive gathering of the raw materials from our network of small domestic alpaca farmers worth the effort.

Alpaca fibers have a unique characteristics which aids in their ability to regulate temperature in both cold and hot environments. In fact, Alpaca fibers are up to 30% warmer—or cooler—than wool, and have a greater moisture wicking ability and more natural loft. And it doesn’t stop there.

The Alpaca Fibers are processed and cleaned with a biodegradable citrus-based cleaner, making them completely renewable and environmentally sound. ALTERA High Performance Alpaca Fiber Technology is naturally anti-microbial and flame resistant. In addition, ALTERA enhances the anti-microbial nature of the fiber with exclusive Silver Infusion Technology, enabling multiple, odor-free wears of our alpaca garments without laundering.
