Alan H.wrote a review of Arc'teryx Gamma MX Hooded Softshell Jacket - Men's on February 12, 2012
I really, really love jackets. Currently rocking the Arc'teryx Alpha SV, Arc'teryx Gamma MX, Arc'teryx Strato Hoody, The North Face Scythe Fleece, MontBell Thermawrap Parka, MontBell Ultralight Thermawrap, and of course - the Arc'teryx Gamma MX Hoody. When it comes to insulated jackets, I have to give MontBell the nod. But when it comes to pretty much everything else, Arc'teryx delivers.
This hoody is by far my favorite jacket. People complain about it letting in too much wind and not being waterproof but that's why you get the Alpha SV jacket. This thing handles any amount of snow and it can handle a good amount of rain (trust me, that's all we have been getting here in Utah this season). As long as you wear a nice long sleeve base layer, this thing pretty much windproof.
I've actually been comfortable down to the 20's with a performance base layer on underneath while doing light activities (walking, shoveling). I'm fine in the 30's wearing a t-shirt just sitting around. But it also has been great for when we reach the 50's and 60's. It really does insulate well in cooler weather and it breathes well in warmer weather. Exactly what you want.
Pockets are big and in the right spots. Cuffs fit great. Hoody adjusts perfectly. Zippers are legit. The fit is superb. And the aesthetics make other jackets in the room just plain jealous.
I'm a bigger dude at 6'4" 250 lbs and the XXL fits great. Leaves enough room for a fleece or insulated jacket on the colder days but is still able to form fit with just a t-shirt. The best jacket I've ever owned - 'nuff said.
