Benefits of Merino Wool

  • Moisture Wicking: Absorbs sweat directly from skin and releases it outward into the air to keep you dry and comfortable.
  • Soft & Comfortable: Ultra-fine 17.5-micron fibers create a luxuriously soft hand that will not itch or irritate sensitive skin.
  • Highly Breathable: Natural fiber structure circulates air freely to regulate body temperature in both warm and cool environments.
  • Naturally Anti-Microbial: Resists odor-causing bacteria so garments stay fresh over multi-day adventures and travel.
  • Insulates When Wet: Holds up to 30% of its weight in moisture without feeling clammy, retaining thermal efficiency when damp.
  • Naturally Fire Resistant: Self-extinguishing fiber that will not melt or stick to skin when exposed to sparks.
  • UV Protection: Inherent UPF 25 rating provides natural sun defense for long outdoor trail days.
  • Renewable & Biodegradable: 100% natural fiber shorn seasonally from Australian Merino sheep with a minimal environmental footprint.
