Arms of Andes Women's Alpaca Wool Base Layer: 300 Lightweight Half-Zip

Our all-purpose base layer's versatile design looks elegant in the city but is constructed for all outdoor activities. Our fleece is ideal as a wool ski sweater in the winter or a breathable hiking base layer in the summer. Made from 100% Royal Alpaca Wool, our base layer feels soft & light and has a half-zip for added temperature regulation.

• Alpaca fiber outperforms merino in warmth and weight. No synthetic fibers, no compromises.
• Ultralight and packable, delivers real warmth in deep cold without bulk under a helmet or hood.
• Natural keratin structure resists odor buildup, air it out overnight and it's ready to wear.
• Semi-hollow core Alpaca fibers resist pilling and maintain their structure through years of hard use.
• Sourced from Peruvian Alpacas adapted to centuries of extreme Andean weather. Performance that's earned, not engineered.
