This is a great technical shell. It has a perfect amount of room for multiple types of layers without being too tight or baggy. With a T shirt, it works and looks great for warm weather rain. For cold weather layering, I could fit a Patagonia hooded down sweater on with a fleece on and not feel too bulked up or restricted. The 3L facbric and inner lining material is very durable and smooth. Layers slide in and out easily.
The YKK zippers are similar to previous RIRI zippers, except the teeth are smaller and the zip is cleaner and smoother. They are also more flexible which is great when sitting or bending over.
The jacket has a great cut and does not ride up at the hip or sleeves when reaching etc. The internal pow cuffs are a nice feature when wearing it, but I have big meat hooks and when I pull my hands out, they get caught in the pow sleeve and end up pulling the sleeve inside out. Minor complaint- can always cut them off. The jacket zips up perfectly around the face and hasa high collar. The hood is very adjustable. Between the two, no snow is going down your neck. I am 6'2, 200lbs and have a 45" chest. The xl fits like a dream. I also have a big chin and can fit my face in fine behind the collar-just a perfect amount of space.
The jacket works well while wearing a backpack. All zippered pockets are accessible with a pack on. I also can fit one splitboard skin (G3) into each chest pocket. There is an interior fleece pocket for an ipod etc. which is a nice feature. Underarm pit zips are not meshlined, but open and close well with a smooth zipper.
Overall- great technical shell that can be worn 4 seasons. The material is a great choice and the fit allows for technical applications but also has style- not a tight tele-skiing Arc'teryx style!
