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