How to Measure

Hand Measurement Guide

Your Isolation Harness must fit snugly for optimal performance and control.
Please follow the steps below to measure your hand properly before selecting your size.

Step 1 – Wrap a Soft Measuring Tape

Wrap a flexible tape measure around the widest part of your knuckles, excluding your thumb. This is usually across the base of your four fingers.

Step 2 – Measure Again

Remove and re-measure two more times to ensure accuracy. Hand swelling can slightly alter sizing, so we want your true average.

Step 3 – Take the Average

Add all three measurements and divide by 3. This is your final number.

Size Chart

Use your average knuckle circumference to select the correct harness size. The harness should fit very snugly. Purchasing a size too large will dramatically affect performance.

K1 – 6 1/2" se 7 1/2"

K2 – 7 1/2" se 9"

K3 – 9" se 10 1/2"
