The Kari Traa Lam Half-Zip is a super-soft, super-smooth, super-breathable, 100% Merino wool longsleeve women’s baselayer pullover with a feminine pro-sport look. Ergonomic lines flatter and, together with 4-way stretch fabric, give you a slim, snug fit. It’s naturally odor-resistant and strategic mesh ventilation stops you from overheating. Flatlock seams and super-fine wool give you ooh-factor coziness. An all-season must-have.
