The TempSync T-Shirt Bra is an everyday foam-cup bra built around 37.5 Tech fabric, which uses natural minerals to move moisture and heat away before you feel overheated. It pairs perforated cups and a flexible, poke-free underwire with convertible straps that switch to an X-back, plus a tagless label. It is aimed at women dealing with hot flashes or anyone who runs warm under a T-shirt. Against standard breathable bras, the thermoregulating fabric is the differentiator; the trade-off is that it is still a wired, molded-cup bra rather than a seamless or wire-free design.
