The IBEX Women's Woolies Pro Tech Crew is the ultimate long sleeve wool shirt women choose when they need a high-performance base layer that can transition from mountain trails to city streets. Designed with Nuyarn spinning technology, it delivers 35% more warmth, 85% more stretch, and nearly nine times the durability of traditional merino—making it one of the most advanced merino wool shirts for women available. Made from a premium blend of 85% merino wool top and 15% nylon at 125 GSM, this garment offers incredible softness, lightweight warmth, and exceptional breathability. Unlike heavier thermals, it won't overheat you indoors or weigh you down during activity. Whether worn as a thermal shirt women need for winter hikes, a merino wool t shirt alternative for travel, or part of your womens merino wool base layer set for it's a piece you'll reach for in every season. The thoughtful design includes raglan sleeves for maximum arm mobility, flatlock seams to prevent irritation, and thumbholes to keep your sleeves secure during movement. This makes it perfect as winter hiking shirts women love, a merino running shirt for workouts, or simply a cozy wool long sleeved shirt for lounging at home. Lightweight and packable, the Woolies Pro Tech Crew takes minimal space in your luggage, making it a must-have for camping, trekking, and cold-weather travel. Whether you're layering it under a jacket on a snowy mountain or wearing it solo on a cool morning hike, this wool t shirt women depend on delivers all-day comfort, performance, and timeless style.
