The Lam Long Sleeve is a super-soft, super-smooth, super-breathable, 100% Merino wool women's baselayer top 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 next-to-skin comfort. Definitely a must have for every season.
