Sizing Information

We checked the sizing of this style with our Fit Check mannequins Huey and Dewey. They are wearing size Medium and XL jackets respectively. These are their “usual” sizes and they fit just fine. We also checked the chest and belly of the other sizes and find them to fit OK too. Therefore, we recommend you choose the size you normally wear in men’s clothing.

We developed the size chart below to help you choose based upon your chest/sleeve measurements. The chest measurements come from our observations and measurements and the sleeve lengths are from Cortech (which we find to be a good estimate).

The “cut” of this jacket is geared toward street or sport riding, and the overall fit is “casual” (meaning not super snug like more race oriented jackets). We describe the fit of the jackets with the liner(s) installed and the jackets will be more roomy when not using the liners. For this reason, we recommend that If you find yourself between sizes, choose the smaller.

The jackets taper moderately from chest to waist… about 4”. If you have a bit of a belly, just make sure your belly size isn’t too big for the jacket size you choose. For example, we list the size XL as a 46 max chest and so the max belly for that jacket would be about 42. If your belly/waist is smaller than this, it shouldn’t be a problem because the jackets have a lot of adjustability in the waist.

Tall sizes: The standard sizes in this jacket will work for the “average height” rider. Tall sizes are approximately 2” taller in the sleeve and torso. Sleeve lengths listed in the chart below are from the shoulder seam to the end of the arm cuff.

Alpha Size Max Chest Size Sleeve Length Tall Sleeve Length
XS 38 25 -
Small 40 25.5 -
Medium 42 26 28
Large 44 26.5 28.5
XL 46 27 29
XXL 48 27.5 29.5
XXXL 50 27.5 -
XXXXL 52 28 -

Our Two Cents

For 2016 Cortech has updated the GX Sport Air 4.0 Jacket… but only slightly. The previous jacket(s) are a staple of their line… a mesh shell with a dual liner system to extend the usable comfort range. It has all worked very well in the past and is a popular style, so why mess with success, right?

So what’s different? The styling is slightly updated and the armor used in the jacket is a molded CE style rather than the hard plastic over foam units.

As I mentioned the shell is almost completely flow-thru mesh so this jacket is going to be comfortable in nearly any warm/hot weather. Having a good mesh style in your close is a must for most of us that have a hot summer. But this jacket goes a bit beyond what most mesh styles offer. Most come with a removable windproof/waterproof liner and this one does too, but you also get a vest-type thermal liner which makes the jacket comfortable in cooler weather. Maybe not cold weather, but it will cover three seasons at least.

For impact protection you get elbow and shoulder armor which is the molded rubber CE rated protectors like you find in almost any new style jacket these days. And the back pad is a lightweight energy absorbing type. To enhance the jacket’s abrasion protection characteristics, there are heavy duty textile overlays on the shoulders and elbows (the most likely impact areas).

This jacket packs a lot of functionality and temperature control for a very affordable price. And the styling is nice too. Almost any rider will get along well with the colors and graphics.

Size Medium on the jacket was perfect. I weigh 170 pounds, 5'6" tall. Jacket has enough room to wear office attire under the jacket - or just a "T". Protection is great - air flow is great!. As usual, Motorcycle Gear was great to buy from!
