Alpinestars MM93 Austin Waterproof Jacket (LG - XXL Only)

These jackets are sold in US based “alpha” sizes. This particular style fits much like jackets in Alpinestar’s Urban collection and it runs just a bit smaller than their other jackets… I’d say about 1/2 or even one full size smaller. If you have a pretty trim build and prefer a trim fit, you’ll likely find a fit in the size you normally wear in men’s clothing. If you have a more stout build, you’ll probably wind up in a jacket that is one size larger than you normally wear. We measured each size in this jacket style and developed the size chart below. Just measure both your chest and your belly and then choose a jacket size that will accommodate both.

About sizing when accessory armor is used: I’d recommend you add 1” to your chest and belly measurements if you plan on adding the chest pads and the KR-1i/CELLi back pad, which will be most peoples upgrade choice. If you want to add the KR-2i back pad, add 2” to both your chest and belly measurements before selecting from the chart.

The Alpinestars MM93 Austin Waterproof Jacket is part of Alpinestar’s MM93 collection of riding apparel which is endorsed by Marc Marquez. This is a great jacket for the everyday street rider. Shoulder and elbow armor is supplied with the jacket and a back protector is optional. This jacket has bulletproof waterproofing capabilities and a great thermal liner for cold weather.

The overall fit of this jacket, I’d characterize as “standard”... not super sporty, but not “relaxed” either. We did find the overall fit to be trim (see our sizing advice about that) so be sure and measure yourself before selecting a size. I think the sporty MM93 graphics give this jacket a bit more of a sporty feel than some of the standard Alpinestars products but many of the practical features and armor options are the same.

This jacket is equipped with a fixed waterproof liner which is between the outer shell and inner lining. The fixed liner will be very effective in keeping water out, and there are a couple zippered vents in the side torso area to admit a bit of air, but the venting doesn’t pass all the way through the liner to your skin like with some more elaborate designs. With the vents open, I think you can achieve comfort in milder weather, but not hot (or even warm) weather. But this jacket does come with a removable full thermal liner which feels nice and should give lots of warmth for colder weather.

Other features: A waterproof breast pocket just inside the main zipper (idea for your phone); Reflective strips on each bicep for night visibility; A full around zip to connect to Alpinestars pants; Adjusters for the waist fit and also the fit of the arms.

Like most Alpinestars street jackets, this one has excellent armor capability. The jacket comes with removable CE protectors in the elbows and shoulders. And it has a pocket to install the optional back pad. We have listed the options for upgrading the back protector below. For a lighter weight jacket like this, I’d recommend the KR-CELLi option so the weight and thickness of the back protector doesn’t overwhelm the jacket chassis, but the KR-1i or KR-2i works as well if you are really concerned about getting the very most rugged back pad you can. :: Paul, 05-03-21
