Start with the Product You Want to Size
1
Measure Chest
Measure around the fullest part of the chest while standing naturally. Keep the tape level and snug, not tight.
2
Measure Waist
Measure around your natural waist or the position where the belt or harness waist pad will sit during use.
3
Measure Thigh
Measure around the upper thigh where the leg straps will rest. This helps improve comfort and adjustment range.
4
Measure Height and Body Build
Use height and body build as a secondary check, especially for dorsal D-ring position and torso adjustment.

FAQs
Common Sizing Questions
What if I am between two sizes?
Choose the size that gives correct D-ring position and safe strap adjustment range. For bulky winter clothing, consult the model-wise size chart or contact our team.
Can one size fit all workers?
No. A poor fit can affect comfort, adjustment, and confidence during use. Size selection should match the wearer and the application.
Do all harness models use the same size chart?
Not always. Comfort padding, webbing geometry, belt design, and attachment points can change the fit. Keep model-wise charts wherever the pattern changes.
Can I wear a harness over a jacket?
Yes, but the final size should be selected based on actual wearing condition, especially for winter clothing or industrial uniforms.
