The Ibex Men's Woolies Pro Tech Crew is our lightest weight base layer, engineered to excel in cool to cold conditions. Featuring Nuyarn technology, it enhances merino wool's performance, making it 35% more thermally efficient, 85% more elastic, and 8.8 times more durable than traditional ring-spun merino. Designed with raglan sleeves for unrestricted movement, flatlock seams to minimize chafing, and thumbholes for easy layering, this crew ensures comfort and flexibility during any activity. The nylon core adds durability, making it an ideal choice for demanding adventures.
