I got my Montbell Parka today. It's the newly revised parka in Men's size Medium. Color is Olive Green.
FIT
First off, I tried it on. I am 5'11, 160lbs and to my relief the fit is good (I hate ordering expensive clothes online). The length in the sleeves is good. Shoulders fit well and the chest is a bit roomy, but that's probably good because I only have a tee shirt on underneath.
The length of the jacket is just long enough. If you are any taller than me, I would opt for a bigger size. The only area that wasn't perfect was the waist which was a little big (photo 1) but that was easily adjustable with the new waist cinch cord. Here's a photo of the cord without the waist tightened.

With the waist cinched, the fit was good. To cinch the waist you can lift up the hem near the main zip and tighten the cords, or you can tighten them by putting your hands in the front pockets and pulling on the bungie cords there. The bungie cords enter the pockets in the inner corner so you can actually tighten/loosen the waist hem without taking your hands out of the pockets. Kind of a neat feature. This is the easiest way to adjust it, but it does mean there is about 4 inches of bungie in each pocket. This probably adds a 0.1oz or so.
Notice how the length is borderline long enough. Some might prefer a longer jacket but this is normally how I wear my jackets so I'm happy with this.

Two more views:


The waist adjustment is definately an appreciated feature, although I would be happy without it IF the waist was tighter. They would need to reduce the circumference of the waist by about 4-5" to fit me nicely without a cinch cord. I would be okay with this jacket as is without the cinch, but it's certainly appreciated.
The hood cinch seems less essential, but perhaps I won't feel that way when I'm caught in really cold weather. The hood fits well without any cinch if I do the zip all the way up. There is an adjustment on the back of the hood that lets you control how much 'beak the hood has. This works well.
As you can see in the second photo of the back of the jacket, there is stretchy triangles of fabric at the wrists. For me, the wrists are not tight enough to start stretching these areas, but someone with larger wrists may find this gives a nice seal.
WEIGHT
Now for the exciting part….how much does it weigh? On my scale, the parka without fabric tags removed weighs 242g or 8.52oz. Montbell claims 9oz for size medium, so my parka is about 1/2 oz under spec, which I guess is good.
The supplied stuff sack weighs 7g (0.25oz) and is a good fit. It matches the color of the jacket which is nice. The size of the parka stuffed is slightly bigger than a rolled NeoAir. It seems about as long as a 1L Nalgene, but a bit thinner.
LOFT
Using a digital caliper, I measured the loft of one of the chest baffles at 1.1" or 28mm….pretty good! This is the loft at the peak height of the baffle. There is a bit of variation between baffles, but the main baffles all seem to be between 3/4" to 1.1".
