I have the Morra pant, nice pants! I just warrantied the zipper on them. I've honestly hardly worn mine as they are a "boring" gray.When you're talking about a rain jacket, sure. Especially with a few models that just use an open mesh. Dirt, oils, & sunscreen will get through to the membrane much easier in a 2L vs. a 3L. I keep my climbing kit 3L on bottom and 3L Pro on top and fangirl the Dead Bird brand pretty hard. But similar to how the OP is looking for something warm, I ski in insulated gear top & bottom (Arc Morra pants - RIP, one of the most bomber 2L pants on the market - & the MHW Barnsie). You have to be pretty dirty for skin oils to get through your base layer, a polyester taffeta lining, and a few grams of insulation for lining to get shot.
I disagree that outer fabrics don't matter. I remember talking to a guy on here about a year and a half ago who had a Mountain Hardwear stretch jacket of some sort where he was upset with how fast it started pilling. There wasn't any spandex in the fabric content, so all of it came from mechanical stretch - looser knits or stretch wovens that are woven loosely & shrunken down. Both leave a lot more of the fiber exposed and can pill in the wash or rubbing against pack straps. Most non-stretch wovens will come out of the pill tests with scores in the top range, but I've definitely reviewed swatches that don't, especially in the lower denier fabrics.
As for the Primo, it was a 2L. I'm not really surprised it got dropped. Insulation was an 800+ down, which was an odd choice since it's compromised when wet, and most people sweat a bit over the course of a ski day. Also odd to chase a high fill power since most customers aren't obsessed with optimizing packability or cutting a few ounces out of their ski kit compared to the hiking/climbing community.
This is a really interesting thread for those of us who are not well-versed on the different fabrics, etc.
