Seamless sports bra in Heather Gray is super comfortable to wear. It is made in a multi-knit airy but strong material. It has a switch back with a wide band at the bottom, which means that it is much less burdensome on the neck than other types of sports bra. Padding in cups that can be removed if needed and wide elastic under the bust.
This is completely normal in size, so choose the size you usually wear.
