I wear this jacket all the time. I'm based out of Washington and with the minimal rain we get comes cold mornings and nights. I use this jacket as an insulation layer allowing the down aspect of it to trap my body temp. It's either used as an outer layer or underneath my rain jacket. The fit is perfect. It has the extra long back which prevents it from riding up while my pack is on. While at the same time stopping any unexpected breezy from traveling up from underneath. I love the hood, which is adjustable allowing me to sintch it down and form to my head. The jacket is extremely packable, and fits inside of it's own pocket. First Lite crushed this one out of the park and this jacket will see many early spring and late fall hunts.
