Overall, I like it, and am going to keep it.
Pros: REALLY light, packs down REALLY small (I fit it in a box 7" x 4" x 3" without really squishing it down). I drove home with the A/C on, and it was a reasonably cold day, seemed warm enough. I'll have to re-post about warmth, after I try it out in the field. The Pertex Quantum Exterior seems water resistant (it's raining here today and shed the rain pretty good walking from car to home, etc) but I doubt it would hold up for long exposure.
Cons: Don't REALLY care for the color (see pictures) I got the "Excalibur/Vintage" color. The exterior (Excalibur) is a purplish grey, which seems alright. And the interior is purple (Vintage), why Stoic can't make awesome gear, in not so "fabulous" colors is beyond me. All in all, this isn't such a big deal. The cuffs look like rigid webbing in the photos, but they are softer, so I like that. The problem is they are REALLY tight, I like to be able to shove the sleeves up my arm if I am doing something with my hands, and this makes it kind of hard to do. I guess since they are fairly long (1.5") it means you wont really have much material getting in your way, but still this tightness is pretty awkward, hopefully they will loosen over time. If you have big wrists (which I dont) this might be a problem for you.
Fit: I am 5'10" 175, and the M fits me well (see photo)
