The cuffs aren’t velcro closures, but some kind of elastic closure that works very well for sealing. Well enough that if you had very big wrists it might be a bit of a pain in the ass getting it on /off.
If there was a likely chance of steady rainfall lasting hours or into days, I’d pick the regular Dewpoint. When it looks like occasional showers (or no precipitation) this is the jacket I’d choose—which in Montana anyways is the vast majority of time.
Also if you know you’re going to be busting a lot of brush, you might want a heavier fabric rain jacket.
