I've been looking at the same think; was on SAC yesterday sometime for less than $100, which made it a pretty good deal. I've got a 7-oz Montbell with 2-oz of down in it that works very well, so I'm not in the market right now, but it's still tempting to try it out -- I like the anorak style.
Women's colors are better -- I had considered getting the gray anorak for her that Stoic just released, but she's already got a Stoic Down Sweater, which fits her very well, though it's heavier, at just under 11oz.
If anyone bites on the Hadron, I'd love to hear impressions. If it's like all the other Stoic/BC stuff, sometime in the next year these will be available for 50%+ off, which could make them a killer deal.
