FIELD NOTE / 01

Measure the body.
Not the label.

Waist and thigh ranges do not move together across brands. Take both measurements where the harness actually sits, wearing the layers you expect to climb in.

How to measure correctly →

Five brands.
Five sizing patterns.

Not your trouser size.

  1. WaistWrap a soft tape around the point where the waist belt will sit, above your hip bones.
  2. ThighMeasure the fullest point of one upper thigh without pulling the tape tight.
  3. LayersMeasure in the clothing you expect to climb in. Winter layers can change the shortlist.

Charts narrow the field.
Hanging confirms the fit.

47 sourced rulesNo generic clothing conversion and no inferred thigh ranges.
