Familiarity: I've put it through the wringer
I've had these for several years, and have used for road cycling and occasional off-road cycling. The Amphib material is soft, somewhat stretchy, though not as much so as the stretch fleece used to make the back of the tight. The Amphib stuff is also water-resistant, and dramatically wind-blocking, and the combination is near-perfect for a road tight: the warm fleece in back also lets moisture escape, while the Amphib front tames the wind chill of riding in the cold. The back doesn't fend off spray, but most times will stay warm despite getting damp. Snow and rain (well, at least light rain; I tend to pull of it's coming down in buckets) just bounce off the Amphib. Nice.
Fit. I'm 6'1, 200 lb more or less, 32" inseam, 36" waist. A size Large fits me well - snug, but with room for a padded short beneath. Just what I want for cool-weather riding. They've held up well for about 10 years and several crashes. A hint: use the waist drawcord; the Amphib fabric has a tendency to pull down the waist of the tights. Otherwise these my favorite cold-weather bottoms (anything below 50 degrees). If I still ran trails or XC skied I'd use the Amphibs even more. One of those garments that just works..
