Such a simple-looking jacket; the temptation might be to not take it as seriously as some of Arc'teryx's other pieces. But the kimono-esque, minimal looks belie the functionality: super-breathable outer shell that's totally capable of shedding snow and rain, the hood articulates with head movement really nicely, the fleece lining is beautifully designed to keep the wearer warm. Add to that all of the usual Arc'teryx touches (seams, arm and elbow articulation etc.) and it's a jacket that's capable of much more than it might first appear. I reach for this one as Im headed out the door into weather every time.
Ill add my two cents to the Hyllus v. Firee discussion , I've worn both extensively. Similar looks, same fleece lining, but past that theyre two very different jackets. The Hyllus cut is trim, the Firee generous (by Arcteryx standards). The Hyllus outer fabric does NOT cut the wind nearly as well as the Firee's shell, based on my field tests (25+mph wind speeds in 30 degree weather) and as indicated by Polartecs website. The Hyllus cuff design is clearly meant to help with layering, and an internal pocket is conspicuously absent. Ultimately, the Firee is the last thing youll put on, whereas the Hyllus is meant for layering. Both great jackets, but make sure you soak in all the good reviewer commentary and tech information as you make your choice!
