The fabric is the most water resistant non-coated or laminated fabric I know of, hence the name DUCKSBACK—as water runs off of the fabric like water running off of a duck's back. Completely vapor permeable.
These are insulated chaps. They were invented/designed by a man in Anchorage, Alaska and were tested at Fort Richardson, AK. If it is cold enough to need long underwear in the morning, but too warm to still have them on by late morning, LEG JACKETS are the answer. Easy to put on or take off. Full-length two-way zippers and a 1" web belt with a side release buckle to put through your belt. They weigh 8 ounces per leg, and can stuff into a 6"x12" stuff sack.
Wiggy,
Just got off the tractor after fixing the driveway from recent storm damage while it was still raining. Not that it was all that cold but I figured the rain would help me test out the ducksback material and I must say I was impressed. Picture sitting on a tractor with no cover from the elements and all the rain falling on the top of my body being channeled down to my legs. After a couple hours my legs were still totally dry. As far as I can tell, the water didn't penetrate the insulation at all. It simply rolled off the exterior of the fabric. It should also be noted that while the leg jackets were too warm for this application I still didn't sweat in them. I can't think of another insulated product that would behave this way.

The primary function of this product is to keep your legs warm and dry in winter weather. It does so admirably. In spring and fall weather near the freezing point, they are very warm gaiters that protect your legs against wet weeds. An interesting and valuable aside, in emergency situations they can be zipped together to form a tube for emergency bivouacs. I suggest a slightly larger size to enable you to slide the tube up over your torso could be desirable. It also allows a moderate extension of sleeping bag temperature range as well.
