Proton Hoody
I got 3 of these and all were loved by the recipient. Good as an underlayer and as a spring jacket. The large gave some extra room near the tummy. The recipients were 5'10 to 5'11 and around 165lb

Janet S. Skip Rated 5 out of 5Great Mid Layer
The Proton FL is an excellent mid layer. I’ve come to prefer it over the Atom Lt for shoulder season outdoor activities. The 4 pockets are very useful and the jacket breathes very well. I usually wear it under a shell. The fit is definitely slim so if you’re between sizes then size up.
Thanh Rated 5 out of 5Very tough and breathable piece
Just like almost every Arc'teryx piece I bough, the fit is exactly as I expected. That being said, I feel like over the years Arc'teryx is fit is less specific than it used to be. This piece is not articulated for overhead reach than my 4+ years old Proton LT. Like the Proton LT it is very tough and breathable. I wear it running and find it comfortable at 7c with the jacket unzipped. At -10c with a mid-weight base layer, it was getting cold. XC skiing at -5c to -10c was perfect. The fit was good for me at 5'9" and 165 lb with a climber build. Tall guys will probably find the sleeve a bit too short. The good is not insulated so you might need a toque. My only concern is that the insulation is literally breaking up. Instead of synthetic hollow fiber, it more like hair/needle which might feel a little weird next to the skin.
