  1. Sleeve __

Measuring a motorcycle jacket alone is not good. Please help to confirm the proper sleeve length by measuring a Dress Shirt Sleeve length as shown below. Also make sure to mention when providing this measurement, that this is a dress shirt sleeve length not a jacket sleeve length measurement, measured as shown in Sizing Detail.Note: Your dress shirt sleeve measured as shown above should be approximately 2″ shorter than the jacket sleeve length measured. Please advise if you ride a sportbike leaning more forward, stretching the arms out futher.

  1. Crotch to start of knee armor. ______

(For proper knee armor location.) It is almost impossible to find a production pant where the knee armor fits perfectly on the kneecap when in a riding position. Knee/shin is one of the highest initial impact areas of the body in a tumble. If the armor floats up and down in the pocket, it will not stay in place upon impact. If the armor can be adjusted with Velcro, the Velcro can detach in a tumble  Follow these instructions to measure for the correct placement of knee/shin armor and inseam:
The best way to start is by wearing a denim pant, sitting with your knees bent at a 90 degree angle, shin vertical to the ground, leg horizontal to the ground. (We will explain later how to measure if your feet are further back on the pegs, or more forward) Thin dress pants or cotton/polyester pants will not work properly for measuring.
Place a ruler up against the shin bone with another ruler touching on top of the leg. The knee/shin armor starts 1.5″ back from the intersection of the rulers.

Here you can see the vertical plane of the shin and the horizontal plane of the leg with 1.5″ back from the top of the knee towards the waist marked with the finger.

Put tape around the top of the knee 1.5″ back, with the tape extending down to the inseam of the pant.

Straighten the knee. From the top tape line go down the leg 5 inches and put another tape line. You have just marked where the knee armor will go

The photo above shows a good inseam length. The cuff of the pant should be close to or touching the top foot arch of the boot.
Place a cloth tape at the crotch where all the seams of the pant intersect. Measure down the inseam to where the tape wrapped around the leg intersects the inseam. This measurement is called: “Crotch to the starting point of the knee/shin armor.”

This photos shows our standard Knee/Shin Tri-Armor in the proper location on the knee.
