We tried the size Medium in this jacket on Huey and we put an XL jacket on Dewey. These are the sizes they normally wear and both fit great. My advice would be to wear the size you normally wear in men’s clothing.
If you look at Icon’s chest size estimates for each jacket, you might be choosing a size larger than you normally wear (for example a person with a 46 chest typically is an XL, but using Icon’s chart you’d buy an XXL). If you use our estimates of max chest, you’ll probably be choosing the size you normally wear.
Contrary to Icon’s marketing info which says this jacket has an “Icon Sport Fit”, which implies a snug torso and a large taper from chest to waist, I find this jacket to be pretty “relaxed” and therefore belly size won’t be a problem for most. But if you have a bit of a belly, you’ll want to get a measurement and make sure to choose a jacket large enough to work.
