We tried a size Medium and an XL on our Fit Check mannequins Huey and Dewey. Those are sizes they usually wear in an “American” cut jacket. This jacket from REV’IT! fits well enough and it looks sharp, but there is very minimal room left. Many brands from Europe exhibit a fit like this, such as Alpinestars. If you look at REV’IT!’s published size chart (below), you’ll see their estimate of chest size is at least a full size smaller than what you’d find in equivalent US designed clothing.
We measured each jacket and tried them on and we’ve concluded that the fit is just about one-half size smaller than what you would find in ordinary US men’s clothing. The amount the jackets are undersized is not as severe as REV’IT!’s size chart would have you believe. For most people, this means you’ll be able to buy the size you normally wear if you want a snug, European style fit. If you want a looser American fit, or if you are between sizes, choose one size larger. I found the Poseidon 2 to fit a bit more closely than other REVIT 3/4 style jackets. Its primarily a street/touring jacket rather than an adventure style, so that is to be expected. So when in doubt on the size, you’ll probably need to go larger.
Below is the REV’IT!-published chest size for each jacket’s alpha size along with our estimate of max chest and max waist/belly. This particular style is not a “sport” oriented style so there is not a lot of taper from chest to waist, and with a style like this you can effectively tailor the fit of the waist with the side waist adjusters, which makes the jacket look great and fit great, so don’t worry if your waist/belly is smaller than the max. We only list this for those that have a belly so they can know what minimum size they’d have to choose to fit the belly.

Sizing Tip for Those Using Upgraded Armor: Adding upgraded back protection and chest pads will take up some room in the jacket so when making your size selection add to your chest size if you plan on using the thicker back protection and/or chest protectors. I’d advise you to add 1” if you use an upgraded back pad and also an inch for chest pad upgrades. So if you plan on buying both, then add a full 2” to your chest size before making your size selection.
