I got this jacket when it was on sale for $188.34 to replace my stolen TNF Thermoball hoodie, which was a size small. I ordered a size small thinking it would be the same fit. While I could zip up the jacket, it was a relatively tight fit so I exchanged it for a medium and now it fits perfectly. I love the two way zipper. The pockets are nice and warm, but I can see how it'd be irritating when you have dry skin on your fingers. It's the kind of material that catches really easy. Personally, I would've loved to see them use a different material like they did the OR Cathode jacket.
Breathability is better than I expected. Went for a stroll downtown in ~35 degree weather and didn't even notice the cold in my chest. Put on the hoody and it was a nice fit. I'm sure this could fit a climbing helmet, but probably not a snowboard helmet. I'll update this review after I give it a try but I'm just judging by the size of the hood.
One thing I was really bummed about was that stuffing the jacket into its own pocket was really hard. I'm not sure if that was an issue with size, I think it's an issue with the design. Outdoor Gear Lab has noted this as an issue as well and I can confirm that that's true. Although it's not a deal breaker, it's still a very comfortable jacket that offers many other features and I am very happy with my purchase.
