How do they breathe on a hard climb?
I live in the south and as such have only worn them for walk-abouts. I have used the Cabela's Microtex a fair amount and I'd rate them as about equally warm, which is pretty warm. You can blow right THROUGH the fabric, much easier than blowing through a windshirt or even a good tafetta with DWR on it. My MED pair weigh 14.3 oz.
I should add that ANY softshell is really intended for mixed conditions, IE, snow/sleet etc and not hard rain/ warm conditions. That nano coating prevents the garment from soaking out and causing evaporative heat loss increasing the hypothermia possibility.
