Most compression bras treat your breasts like potatoes and mash them. The Firm Support Bra II is a different kind of compression bra. It features a reinforced CW-X Targeted Support System, balancing optimum comfort and support for activities ranging from low to high impact. CoolMax/Lycra tricot fabric front panels in perspiration zones and a four-way stretch mesh lining provide maximum breathability and moisture wicking. Offset seams prevent chafing and improve overall comfort.
