I think that they are the Ultimate series of pants.....not really much of a retainer of names of equipment....just kindof get it on and wear it and to find out if it works.
Very quick to dry if there is some of the wet stuff around maybe best with some under long john things when cold. I think that I prefer the gentleman's products from Skye...the Coich stuff a salopette, also good for skiing, not within this category being discussed...if out in the dark or in heavier weather.
Pants, for me, not so warm as the salopette.
