As with all racing safety equipment, racing suit fitment is critically important, and the racing suit user can increase the risk of injury if they are not fitted properly. Please refer to the general racing suit sizing chart below for proper racing suit fitment. This chart is for ADULT racing suit sizing only. YOUTH, JUNIOR and CHILDREN sizes are not included on this sizing chart. If you need a suit size outside of this chart range, please contact our Technical Sales staff for size availability within the Simpson® Safety product offerings.

Properly Measuring Fitment For Simpson® Safety Standard Racing Suits
Locate a cloth tape measure and record the following body measurements:
- A - Height - Stand against a wall, ask someone else to measure from the floor to the top of the head, keeping the tape vertical.
- B - Weight - Using a scale, record the weight of the person being fitted for a driving suit.
- C - Neck - Measure around the fullest part of the neck line, keeping the tape semi-taunt.
- D - Chest - Measure around the fullest part, under the armpits, keeping the tape horizontal.
- E - Waist - Measure around the natural waist line, in-line with the navel, keeping the tape horizontal.
- F - Hips - Measure the circumference around the fullest part of the hips, about 6-7 inches below the waist line, keeping the tape horizontal.
- G - Inseam - Stand against a wall, ask someone else to measure from the crotch to the bottom of the leg.
Once measurements are completed, please refer to the sizing chart below to find the Simpson® Safety racing suit size that best fits your measurements. If you DO NOT find a suit size that works well, you may have to consider having a custom racing suit made by the factory. If this is the case, please refer to the CUSTOM RACING SUIT section listed below.
Remember, a properly fitted racing suit is important for both maximum safety and overall driver comfort.
