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.




Please Provide ALL the Measurements Listed In the Links above in the box to the Left.


• World’s top rated, lightweight, perforated Tri-Armor that fully covers: Back, shoulders, elbow/forearms and chest. 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 Tri-Armor is all perforated and does not make the shirt warmer in hot weather. The armor pulls the material away from the skin making an air space for the perforated armor to breathe.

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. The world’s first all season 3/4 length Ultra II Air Mesh Jacket that will take you from -20F to 85F with optional two part Waterproof/Windproof/Breathable zip in Aero-Tex liner. Remove the liner and have a fully breathable jacket or pant that will take you from 60f to 120F. You don’t need two or three different riding outfits for different weather. The Ultra II Air Mesh jacket is great for any weather.
See: Why remove the Aero Tex in Motoport’s Dictionary. Only the best materials are used. Ask what the other brands of textile Jackets and Pants are made of. The majority today are made of Polyester that has a 100% Polyurethane Coating. Polyester has poor tear/abrasion strength, short life span with poor tolerance to UV rays, along with a very low melting range. Adding Polyurethane coating to Polyester is like adding gas to a fire. Sliding on pavement with any other textile jacket or pant is not safe. Motoport has seen many riders with permanent skin damage where the Polyurethane coating melted into the skin. (See Polyurethane in Motoport’s Dictionary)
The new Marathon Jacket material has the highest tear strength of any motorcycle jacket ever made! 500 Denier Cordura (the best material companies use for overall construction will tear at 22lbs). The Stretch tears at 420 pounds. Take your body weight and multiply that by the speed on a motorcycle. 
 All the other nylon jackets and pants made can tear at a low speed tumble! If the best material of all other synthetic jacket/pants tears at 22lbs. imagine how poor the seam strength is! No other leather suit or synthetic suit has proper seam strength. Motoport Safety Lock Stitches all of the construction seams that will provide more than 2000lbs. of strength.
Abrasion strengths of Polyester are not even close to adequate for riding a motorcycle on pavement. Click on “Save Your Hide” to see more on material strength.. Also Click on “Testimonials” to read stories about riders that love the  Suits.
