Evan E.wrote a review of The North Face Venture Side Zip Pant - Men's on June 2, 2013
The pants do a nice job of keeping out the water as long as the water doesn't go near the zippers. If you sit at all during a rain storm with these pants the water will go right through the zippers. One because the flaps for the zippers face the wrong way so the water will pool up and soak through the zippers and two because the zippers used are just normal zippers with no waterproofing to them. I am 5'8" and 165 lbs and got a medium, its a baggy fit but I think a small would be a little tight for rain gear.
