I know my fleece is the "casual" line, but by material, fit, and weight, it's ahead of the others I looked at and it was a steal. I'm not disappointed.
If anything, I think it looks pretty sharp. I'm not saying I care about looks when I buy technical gear, because I don't, but if I get the bonus of looking professional when I'm guiding a bunch of rowdy 18-22 year olds through the White Mountains, I'll take the boost to my perceived authority and expertise.
Delamination factors on a lot of different stuff, but if Arcteryx backs their gear I'll risk my use falling outside of the "expected." That being said, I don't intend to buy a $600 jacket from them, not remotely. In my eyes, the Patagonia one I found for $150 is already overkill. Rain jackets for my use need to be small in packability and weight, and it's really hard to break over $300 when you're skimping on features and material as much as possible for weight and bulk.
I didn't mean to imply that Arcteryx was the end-all, be-all of outdoors gear, but I DO mean to imply that the items I've seen so far seem to be a cut above, and if others have experienced long-term reliability and good service from this company, I can justify paying out $150 for a baselayer and some more for a pair of pants.
