Sei Mio Core Control Body Harness with Collar and Wrist Cuffs

SEI MIO Core Control is a bondage harness that skips the hour of rope work. It's built from three fit points, an adjustable waist strap, a collar and a central tether, with wrist cuffs that clip on at two heights. You can have someone secured in a minute or two, and it's simple enough that the person wearing it can help put it on.

Two loops, three ways to hold the hands

The central tether has an upper loop and a lower loop. Clip the wrist cuffs to the upper loop and the hands rest near the collar, an exposed, on-display pose. Use the lower loop and they sit at waist height, which is easier to hold for longer. Turn the whole harness around and the wrists are secured behind the body instead. Changing between them takes seconds, so you can shift the mood mid-scene.

Fitting the bondage harness

It's one size, adjustable at the collar, waist and cuffs. Fit the waist strap first, then the collar, then the cuffs. SEI MIO says the excess tether can be trimmed once the fit is set; leave it long until you've tried every position, since behind-the-back needs more length than the front loops.

Comfort and safety

Hands near the collar and wrists behind the back both load the shoulders, so keep those positions brief at first. The collar should never be pulled tight by the wrist tether: if raising the hands tugs on the neck, lengthen the tether. Check the cuffs with two fingers, agree a safe word, and keep safety shears close.

Care

SEI MIO lists spot clean only. Wipe it down with a damp cloth and gentle soap and let it air-dry; no bleach, tumble dryer, iron or dry cleaning.
