Stretch Trousers


The following mentions of the words “Stretch” and “Mesh” refer to the materials Made with Dupont™ Kevlar® Fiber

Here is a pant that looks identical to Duty Pants but much better in every way:

  1. Five times stronger than leather!
  2. Tri-Armor that covers knee/shin and full wrap around thighs providing more coverage than any other motorcycle pant. Tri-Armor molds to your individual shape in 40 minutes or less.
  3. Breathes better than Jeans in hot weather yet works better in cold weather. Water resistant, material dries in minutes after the rain stops. On a bike without a windshield it will take 30 minutes or longer in the rain before the water goes through.
  4. Made in the USA in house by Motoport.
  5. Made custom to fit exactly like your best fitting Jeans NO MATTER WHAT SIZE! If you gain or lose weight alterations can be made.
  6. Machine Washable. Will never stretch out or shrink.
  7. The only material other than leather that is approved for road racing! Four way stretch materials Made with Dupont™ Kevlar® Fiber/Dynatec/Lycra blend that makes these pants more comfortable than Jeans. (See “Save Your Hide.”)

Sizing Guide:
To ensure proper sizing Motoport needs: Height / Weight / Sleeve (from center at base of neck around outside of arms to bend in wrist). To give us the most accurate sleeve measurement, follow the Dress Shirt Sleeve instructions below. Actual Chest / Actual Waist. (No jacket or pant sizes.)Do not inhale when measuring chest. Waist should be measured where you tighten the belt. All measurements taken in a relaxed position. Tape measure should also be comfortable, not tight or loose.NOTE:If ordering Aero-Tex liner we need a neck circumferance measurement at collar height or 2″ from the base of your neck.Follow these instructions to measure for correct sleeve lengthMeasuring 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.

After we receive the above measurements, we will advise if any other measurements are necessary.



  • World's top rated, lightweight, perforated Tri-Armor that covers: . Full wrap around thigh and knee/shin. All Tri-Armor is in Velcro secured pockets and can be removed. Motoport's Tri-Armor covers more of the body that any other motorcycle apparel available. This provides the world's best coverage for over all impact protection. Tri-Armor molds to the body in 30 minutes or less. After initial break the armor becomes comfortable with no restriction of movement. The perforated armor doesn't make the pant warmer in hot weather. The armor pulls the suit material away from the skin providing an air space, allowing the armor to breathe. CLICK HERE to view the pant Tri-Armor.
  • Entire outer shell is made of 4-way Stretch for comfort. The four way stretch material allows you to wear the optional Aero-Tex Pant Liner for cold/wet weather or wear thermal underwear underneath. The material will not conduct cold or heat like leather or nylon, so even the black color works great for hot weather. Note: All the current black Stretch is made with a new invention called "Cold Black". The new black color made with this Cold Black stays 15 Degrees cooler than the previous black color. When touching the material it is actually feels cold. The Cold Black is in the dye of the material and will always work.

  • Zipper fly with Velcro adjustable waist. Belt loops to use a standard belt.
  • Zippers are top quality YKK.
  • Hydrophilic Nylon Mesh Lining on the inside. The Hydrophilic Lining wicks away sweat and makes the liner more comfortable, even when worn directly against the skin.

About materials Made with Dupont™ Kevlar® Fiber

Why is this better? The Stretch is 5 times stronger than leather and less than half the weight. See "Save Your Hide" to learn more about the tear and abrasion strength.

When sliding on pavement with any leather, heat is generated instantly. If no hole is worn through, in many cases, the rider will have a burn under the leather from heat generated from friction during the slide.
