Ski patrollers have to show up for their shifts, no matter what the weather. I've been looking for a rain gear solution for many years, using everything from Gloucester fisherman's duds to ponchos to plastic bags. After extensively reading reviews, I decided to buy The North Face Venture 2 Jacket and Rain Pants.
Yesterday was the first chance that I had to put this combo together. I had a 9-hour shift in continuous rain (1.15" during that period). Temps about 35degF.
I donned the gear in the locker room and headed out to the lifts to start the day in downpour conditions. While water was beading up on the surface and shedding nicely, I wasn't sure if it was still seeping through. About 3 hours in, I went inside of the top house and took off the jacket and pants. My patrol parka, worn underneath, was only the slightest bit damp, and only at the outermost surface (warm and dry within). Same for the pants - my regular Gore-tex bibs were just a bit damp on the outer surface (they are old bibs and haven't had a DWR treatment in a long time). Anyway, 6 hours of rain later, and in the locker room at the end of the day, the gear underneath the Venture 2 jacket and pants were in the same condition - lightly damp on the surface and dry within. I could feel a light dampness to the interior of the Venture jacket and pants, but clearly they were not letting water through in any significant way. Note also that I had a backpack on all day and nothing came through where the straps wear against the jacket. I don't think that the interior moisture came from inside (i.e., sweat condensate); I vented the gear.
So, this system works. Note that I had my standard ski gear on underneath. If you are using this for rain protection in non-winter conditions, I would advise the use of an insulation layer as it does get a tad moist on the inner surface, and that would not be comfortable, say, with only a cotton tee shirt on or with just shorts. You're going to feel moisture and likely feel cold, but you won't get soaked. I'd say you could use these with jeans/hiking pants and a thin Merino summer top and do quite well in wet and warm conditions.
YMMV, but this system worked for me in serious rain conditions.
Sizing... 5'-9" and 150# with full winter gear including a ski patrol parka ... size medium worked well.
