Sizing Information

These jackets are sold in US based “alpha” sizes, so selecting a size is basically pretty easy. For most people, you would choose the size you normally wear in men’s clothing. Alpinestars publishes a super-complicated size chart which can be used to pick a size based upon your chest and waist. We’ve condensed their chart down to make it easy to read (see below). The size Medium and XL fit Huey and Dewey very nicely!


The taper of this jacket is about average (meaning how much smaller the waist/belly is than the chest), and will be great for nearly any type of street riders. Alpinestars’ sizing chart lists the recommended waist range and the jacket has a lot of waist size adjustment. Judging by the way the jackets fit and the numbers in the chart, we feel the “waist” sizes they list could more appropriately be considered belly size ranges (measured right up around the navel area). Your actual jean size waist could be smaller than what is indicated and you’d still be OK.

Jacket Size Chest Range Waist/Belly Range
Small 37.5 to 39 31 to 32.5
Medium 40 to 41.5 33.5 to 35
Large 42 to 43.5 36 to 37.5
XL 44.5 to 46 38 to 40
XXL 47 to 49 40.5 to 42
XXXL 49 to 51 43 to 44.5
XXXXL 51.5 to 53 45 to 47

Our Two Cents

The Quasar jacket is built for summer use primarily. Most of the shell is a mesh material that will allow the air to blow right through. The shoulders and on down the back of the sleeves is a solid textile material. The solid material is used here because these are areas that would most likely be relied upon to protect you from abrasion in case you fell. And solid material is much better able to hold together in that instance as compared to mesh material. The overall design of this jacket is simple and straight-forward. You get the usual storage pockets in front and also a total of four inside pockets (see these in detail by clicking the “View Larger Images” link above). The elbow and shoulders are equipped with CE armor and there are some thin pads in the chest and back. Those can be upgraded with more significant pieces if you like (see the links below). Alpinestars is one of the few manufacturers that offers significant upgrades for the back or any armor for the chest. Their armor is top notch. We photographed the Grey/Black/Yellow Fluo color and found the fluorescent pieces to be nighttime reflective which is a nice touch. I’d not ever seen reflective material in that color…. it is usually white. But in this color it does good in the day and the night! The only minor nit I have with the jacket is that the collar is a higher mandarin style collar. I have sort of a short neck and wouldn’t welcome that in a hot weather style. I prefer a “no collar” style personally, especially in a summer jacket, but I have a short neck, so those with a tall neck will probably like this style very much. This jacket comes with an all-around zipper for connection with compatible Alpinestars pants. Overall, a very nice mostly-mesh style with very high quality materials and finishing. The price is higher than most of this ilk, but if quality is your thing, then you’ll like it. Paul, 09-17-13
