The Long Anatomica is Icebreaker's signature men’s boxer brief in a more extended fit. It’s made with a blend of soft and breathable merino wool infused with Corespun nylon for strength and LYCRA® for stretch. Corespun fabric utilizes nylon fibres wrapped in merino wool for increased durability that still maintains next-to-skin softness. This boxer brief has a contoured front pouch for support and uses a flatlock seam design to eliminate chafing, improving the comfort of its snug fit.
