"I don't know if you can say you're better off going with one of those three. What led you to that conclusion. What are your requirements/priorities?"
– My conclusion is based mainly on price and weight. It's a windshirt. These three look to be less expensive and lighter than my original four.
"Things I would take into consideration in no specific order are cost, weight, hood/no hood, breathability, windproofness, fit, packability, durability, etc. You could even throw looks/appearance on there."
– Excellent advice here, and I appreciate these points. I won't be wearing this around town so appearance isn't terribly important. I'd like a hood, breathability, water "resistance" (this isn't intended as rain gear), and lengthy arms.
"Given all of the tradeoffs, I can't figure out how you pared your list down to the three you've listed. Is it only because those are ones other people in this thread have used?"
– Yep, that's exactly it. I trust the BPL community and I have to start somewhere. As I mentioned, I live in Minnesota where we don't have high alpine winds and low summer humidity. We have high humidity, lakes, temperature swings and bugs. But since I'll be doing some hiking in CO above treeline next month, my best option is to do exactly what you questioned: take the advice of the individuals in this thread. It's why I posted in the first place and, as far as I can tell, one of the main reasons this forum exists. I don't understand your disdain.
Anyway, I'm hearing some votes for Rab and the Houdini?
