SizeWaist rangeHip rangeHow it fits
S/M66-86 cm91-102 cmClose to body, secure through movement. Our smallest size - a 34" waist may feel snug depending on your shape.
M/L86-107 cm102-112 cmFirm fit, designed to move with you. Sits a little higher on the waist with more room across the hips.
L/XL102-122 cm112-127 cmFull coverage, stays in place through extended wear. A longer core and higher waist - fit depends on shape.

The overlap between sizes is intentional. If your measurements fall in the shared range, choose the smaller size for a closer, more secure fit.
