Given the varying temperatures along the trail from portal to peak, curious what people are wearing?

I Usually hike in dry fit top and convertible pants/shorts. Plan to bring one long sleeve mid layer and one hardshell outer jacket. Staying at Trail Camp one night.

Main question is what about pants for glissade? If snow is getting slushy mid-day, what have people worn to glissade down and did it keep you dry for the rest of the hike back to the car? I'm Considering bringing snow pants too, not sure if worth the weight/space.

Thanks! Invaluable source of information on this message board!
