In addition to the previously discussed cuffs, here are a few things I've noted between both jackets:
1) The hood on the MB parka is mediocre. It has tons of adjustability, and a nice hood brim, but the adjustment system is total utter crap. To reduce the volume of the hood so that it fits tight, you have to dig for 2 hidden cordlocks (tucked behind a layer of fabric on either side of the hood), adjust it, and then retuck it back in. This entire process was impossible for me without taking the jacket off and physically seeing the adjustment system. The bill is useless to me…this is a midlayer, not an outer. The bill on my rain jacket will be more useful if I need that protection from rain/snow
Because of this, I really enjoy the simplicity of the Stoic hood. Nice and fitted, with enough room for a beanie underneath. I've used this style hood before (FA down hooded pullover) in conjunction with a Patagonia R1 hoodie style midlayer, and they layer extremely well.
2) Fabric Texture
The MB take the cake, hands down. The MB material offers a very very soft hand, akin to silk, whereas the Stoic has a crinkly stiff feel to it. The Stoic is noticeably louder when handling. Interesting enough, the Stoic uses Pertex Quantum, which is the same material used in BPL's own cocoon pullover. However, I found the BPL cocoon material to be softer and quieter than Stoic's. Not sure how to explain this discrepancy.
If you are familiar with MB, you will recall that MB changed their material around 2008. The Stoic material is extremely similar to the 2008 MB material. Some have described it as "trashbaggy"
Note: This is only meant to describe the feel of the fabric. It's my understanding and intuition that I will benefit more from the Pertex Quantum used in the Stoic jacket. I suspect it is more windproof, and it does indeed feel more durable than the Montbell (an observation I share with William)
3) Full zip vs Snaps
The MB offers a full zip…obviously very convenient but with a weight penalty. The Stoic uses a anorak style half-opening, with 4 plastic snaps at the placket. I'm a little concerned about the plastic snaps. They are fairly stiff, and a bit hard to open once snapped. Metal snaps are easier IMO. My concern relates to the delicate UL fabrics, and how they will fair against the pulling motion when trying to open the snap placket. Just worried that the stiff snaps will rip the fabric that holds them in place…I carefully use my nails to pry the snaps open as opposed to using brute force and tugging on the fabrics to open them.
4) Color:
This is stupid, but worth mentioning. I really like the Excalibur/Vintage color scheme on the Stoic. My photo came out bad…Chris's is much more accurate. It's an awesome gray/graphite/carbon color
5) Hem drawcord
MB uses a complex system that requires adjustment to take place inside the handpocket (where you will find the cord lock). There are two of these on either side of the jacket. Complex and heavy. The stoic uses a very simple 1-hand adjustment system found on the user's right hip. I much prefer the Stoic's.
6) Pockets
MB has 2 hand pockets, while the Stoic has a 1 kangeroo style pass-through pocket.
7) Fit
MB has a more athletic cut overall, but the Stoic has a drop tail for a wee bit more coverage. The MB is cut straight across, both front and back.
8) Weight (Men's Small)
MB- 7.5oz ; Stoic-6.6oz
