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 Alpinestars™ product offerings.  

Properly Measuring Fitment For Alpinestars™ Standard Racing Suits

Locate a cloth tape measure and record the following body measurements:

  • A - Chest - Measure around the fullest part, under the armpits, keeping the tape horizontal.

  • B - Waist - Measure around the natural waist line, in-line with the navel, keeping the tape horizontal.

  • C - Hip - Measure around the fullest part of your hips, about 20cm below waist line, keeping the tape horizontal.

  • D - Thigh -  Measure around the thigh just below the crotch, keeping the tape horizontal.

  • E - Inseam - Stand against a wall, ask someone else to measure from the crotch to the bottom of your leg.

  • F - Arm Length - Measure from shoulder (Humerus) to wrist.

  • G - Height - Stand against a wall, ask someone else to measure from the floor to the top of your head, keeping the tape vertical.

Once measurements are completed, please refer to the sizing chart below to find the Alpinestars 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 for you.  If this is the case, please refer to the CUSTOM RACING SUIT section listed below. 

Finally please remember, a properly fitted racing suit is very important for both maximum safety and overall driver comfort.
