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 waist and upper arms are adjustable with Velcro tabs. Overall this should be a very easy style to fit.

I found the taper from chest to waist of these jackets to be pretty sporty… in other words, those with a belly should check to make sure the jacket size you pick will be big enough for the belly and the chest. In this cut, the max belly is about 4” to 5” less than the max chest size. Example: an XL is a 46” max chest and the max belly would be about 41” or 42”.

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

Not too long ago, I reviewed the T-GP-R jacket for 2012 by Alpinestars and I’m comparing it to this new Viper Air jacket and I’m not finding a substantial difference. The Viper Air feels just a touch lighter overall and it has a vest-type windproof liner so we can’t call it “water resistant like the T-GP-R, but otherwise it is about identical (but $50 less, yay!). A portion of the jacket is made with solid textile material and then there are large panels on the front and back that are mesh. Since the jacket has these mesh panels, a lot of air will blow through onto your skin and keep you comfortable in hot weather. This jacket has a removable windproof vest-liner that will help block the flow thru air which will come in handy during cooler times. You’ll have to take the “View Larger Images” link above to see this liner. We’ve also got a good shot of the jacket’s nighttime reflectivity, so check that out also. It lights up well. The jacket comes with removable armor in the shoulders, elbows, chest and back. The chest and back armor is upgradable (see the links below), so you can consider that for now or in the future. I liked the color scheme of the white and the vivid colors. You’d better be ready to clean the jacket from time to time because that white is pretty lily white and will get dirty easily. Alpinestars mesh styles are a few bucks more than other brands, but the quality shows well and I’m sure you will enjoy using this jacket :: Paul, 04-22-13

Just received my Viper Air jacket, and I love it! The vest liner is a plus for colder days, and it feels like without it it will flow some good air for the summer. I recommend going up one size, as I normally wear a large in most brands. (Read more...)
