I purchased this jacket and the Men's Stagecoach Jacket, which it seems to have replaced, this Spring so a comparison seems apt. Both jackets are roughly the same weight. The styles are quite different but I'll just say that I like both and your taste may favor one or the other.
Overall, the Mountain Trucker jacket is a very nice jacket. The exterior is heavy canvas; tough enough to wear outdoors and not have to worry about rips or tears if you are walking through deep woods or some other inhospitable terrain. The flannel lining is a notch below the Stagecoach jacket (it is looser for some reason) but appears warm and is comfortable. Both jackets fall just below the waist and have enough length to cover oneself adequately (the Stagecoach Jacket actually "dips" a bit further in the back than the front, which was a nice touch). The collars are both canvas so a scarf or something to cover neck will be required in colder weather (unless you go to a heavier coat).
The cut of the trucker jacket is fairly tight although you can easily wear a flannel shirt under it. A sweater may present a bit more difficulty (and this is where the "looser" flannel lining may be problematic). The Stagecoach Jacket had a looser cut, IMHO; even though I got a size smaller than usual, I can still layer underneath it a bit easier.
Both jackets have plenty of pockets (the Trucker Jacket has 7, the Stagecoach Jacket has 8). The pockets on the Trucker Jacket are as follows: two with snap closures on…
