I looked at the FL but it doesn't have a hood so I bought the Kuiu Guide. I really like FL gear but a jacket without a hood is like brushing your teeth without toothpaste - it doesn't work like it should.
Depends upon which FL jacket. The "puffy" has a hood. The Sanctuary has a hood. The soft shell does not.
To the OP; a light windstopper fleece underneath can work wonders, as can a good merino wool layer underneath the jacket.
