The Ibex Women's Woolies Pro Tech Crew is our lightest weight base layer, expertly designed for optimal performance in cool to cold conditions. Utilizing Nuyarn technology, this crew enhances merino wool's thermal efficiency by 35%, elasticity by 85%, and durability by 8.8 times compared to traditional ring-spun wool. The raglan sleeves and flatlock seams ensure a comfortable fit and reduce chafing, while thumbholes allow for seamless layering under midweights and gloves. With a nylon core for added durability, this base layer excels in any activity, providing superior warmth and flexibility.
