Care for your layer

Hand wash or machine wash on a gentle/wool cycle in cold water (50-68°F). Use a mild wool-safe or pH-neutral detergent. Wash with similar colors. Don't bleach or use fabric softener.

Reshape while damp and lay flat to dry. Don't tumble dry, twist, or wring. Cool iron if needed. Store folded in a cool, dry space with airflow; avoid hanging.

The benefits

Why Alpaca wins

Andes-adapted for changing temperatures

Alpacas evolved where days run warm and nights turn cold. Their semi-hollow fibers trap insulating air, helping you stay comfortable as the temperature changes.

Softness starts in the fiber

Alpaca’s smoother scales give the fabric a soft feel against your skin. Comfort comes from the fiber’s structure.

Wear more, wash less

Alpaca wool naturally resists odor. Air your layer between wears, then wash it when it needs cleaning. Less time doing laundry. More time outside.

Single origin

Peru, start to finish.

Arms of Andes is a family company with roots in the Peruvian Andes. “Arms” brings together the initials of four siblings. That connection to Peru shapes what we make and where we make it.

From fiber sourcing and yarn spinning to knitting and sewing, production stays in Peru. One country, with the people and knowledge behind your gear close together.
