Icebreaker Size Chart Combining a classic racerback silhouette with a technical fabric design that's ideal for active pursuits in warm weather, the Meld Zone Sport Bra provides medium support and maximum breathability. This active, slim-fit bra features Icebreaker's super-soft jersey corespun fabric, which uses nylon threads wrapped in merino wool for added durability that retains incredible next-to-skin softness, as well as natural TENCEL(R) and a touch of LYCRA(R) for stretch and comfort. In key areas, the Meld Zone features panels of eyelet merino mesh, to amplify ventilation when you're on the move in hot conditions.
