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. You can also choose a size based upon your chest and belly by using the chart below. This chart is derived from Alpinestars published chart which is in cm units and super complicated. So we condensed their chart down to make it easy to read (see below).

We thought the jacket fit very well, but with both liners in place, they were snug. So my advice would be that if you enjoy a snug, European fit, then choose the size you normally wear. If you like a roomier fit, then go up one size. If you are in between sizes, choose the larger.


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.

When you evaluate the fit of this jacket, you will want to be forgiving if the jacket feels a bit snug with both liners in place. These liners take up room and so if the jacket is not snug, then the jacket will be too loose without the liners. My advice would be to try it on both ways (with and without liners) before you draw any conclusions.

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

About a year ago, almost to the day, I did a review of the then-new Megaton jacket. And this week we are reviewing the 2015 version of the same jacket.

When I reviewed the jacket last year, I raved about the quality and how the pricing was commensurate with less costly brands, but this jacket was a higher quality jacket and therefore was a good value. Well, this year, I can say the same thing, but I’ll have to take the raving down one notch because the price went up approximately thirty bucks.. uh oh. But still… it is a great jacket and a very good value.

The styling is updated for 2015, but there are very few other changes, so I’m going to borrow a bit of the text I wrote about the armor and climate control features from the previous review:

This jacket is a solid textile but has vents for warmer weather. And for colder weather, it has a removable thermal liner. And for wet weather (cold or hot), it also has a removable rain liner. I took a good number of photos to illustrate how this all works together and to show you the individual liners, so take the “View Larger Images” link above to see all those. You’ll be a bit overwhelmed when you first take this jacket completely apart and put it back together, but keep in mind that you won’t be doing this often. You’ll find yourself using a single configuration for a good bit of each season so it won’t turn out to be as much “fiddling around” with zippers, snaps and such as you might fear just taking it all apart at once. I found the whole thing to work as well as any I’ve seen. There is a bit of color coding of zippers to help you keep it all straight.

So aside from the BIG 4 in 1 setup, the textile shell is a straightforward textile design. Like other Alpinestars jackets, it has CE armor and a foam back pad and chest pads. The back pads and chest pads are nothing special, but can be upgraded to something more robust if you wish (see the links below). The jacket has a good storage pocket arrangement inside and out. Thankfully the pocket arrangement inside is duplicated on both liners, so no matter how you have it configured, you’ll have the same storage options.

Overall, I like this jacket and think it is a great value. There are some folks that like the idea of owning one jacket that will “do it all” and they will be very pleased. The overall styling for this 2015 version is updated and the use of multiple colors is sharp (I’ll have to call copycat on the Black/Blue/Grey/Red jacket though… looks SO much like a REV’IT!).
