Most styles are made from merino wool. Some items are 100% merino, while at least one style uses a blend: 85% merino, 13% nylon, and 2% spandex.
They’re offered in a midweight interlock (about 235 g/m²) and a heavier expedition/interlock knit (about 400 g/m²).
Recommendations vary by fabric weight. Midweight items are recommended roughly for active use around 0°F–30°F and for inactive use around 30°F–60°F. The heavier expedition knit is recommended for active use at about 0°F and below, and for inactive use around 0°F–30°F.
Turn garments inside out and machine wash cold on a gentle cycle with a mild or wool-specific detergent. Tumble dry on low. For long-term storage, keep items in an airtight container.
They use flat or flat-lock seams to minimize chafing, and some styles include a gusset to reduce stress in the crotch area.
A covered waistband places merino next to the skin for comfort, and ribbed ankle cuffs help keep the tights in place and make layering easier.
They’re described for everyday wear and outdoor activities such as hiking, camping, biking, running, fishing, hunting, and snowsports.
The listed inseam lengths include 34 inches, 31 inches, and 30 inches across the available options.
The running-style tights use an athletic, flyless design and include a small left-hip pocket (about 3.5 in × 2.5 in) suitable for a card, cash, or keys.
