I like the 150 FL but isn’t that the top w nylon underarm area? Nylon makes me stink so I don’t use those for deer hunting, only game where I don’t care about scent. To be honest I use wool for all of its qualities other than it’s heavier. And having garments that don’t stink is nice, even though I don’t rely on that for deer. I just hunt the wind and watch my routes if possible.
