S/M and M/L Hipbelt

Choose the hipbelt that best encompasses your hip circumference (where you will actually wear the hipbelt). We recommend:

• S/M: 29" – 38" (76–96 cm)
• M/L: 33" – 42" (86–106 cm)

These hipbelts can expand larger than this, but it is ideal if your hip measurement is in these ranges.
