Capri Workout Jumpsuit, Scoop Neck Racerback One Piece with Open Back

A window in the back
The back is neither cut low nor cut straight across. It is an oval opening in the middle of the back, held between the two straps above and a band of knit across the small of the back below. In a heated class or on a long ride that is where air reaches skin, and it is the reason the piece stops feeling like a wetsuit somewhere past the half hour. The band under the opening sits at the waist, level with the denser knit at the front, so the two read as one line rather than two separate details.

Scoop in front, straps that meet
In front the neckline is a deep scoop that clears the collarbone and leaves the throat open. Nothing ties behind the neck: the straps leave the front armhole, cross the shoulder blades and meet at the spine, so the load lands on the centre of the back rather than on the nape. No knot to retie between sets, no loop to loosen before you lie back.

Pads, and no second band
The bust has a built-in bra that holds a pair of removable pads. Keep them in for coverage, take them out if you would rather wear your own. What the bra does not add is a second elastic band under the ribs, which is the part most people feel first when a one piece has been on for an hour.

Hem at the top of the calf
The leg stops below the knee, at the top of the calf. Short enough to clear a bike pedal and a reformer carriage, long enough to cover the knee when you kneel. Hip to hem is one knit with no cuff at the bottom, so there is no band to roll and no hem to adjust when you stand up again.

Colors, sizes, washing
Five colors: black, brown, navy blue, red and plum. Sizes S to L on the chart below. The fit is close through the ribs and the thigh. Between two sizes, take the smaller for a sculpted line and the larger for room across the hip. Machine wash cold and line dry, and let the pads dry outside the bust so they keep their shape.
