Great fit, not too heavy but not flimsy, FANTASTIC polarization, great 3x bifocal magnification. Took these out on the river for a little trout fishing last week and was pleasantly surprised at the quality of the lens, clarity and high quality polarization coating. The magnification strips made know tying a breeze. For references I wear a 7 5/8 in a fitted ball cap or 3 pegs over on a Richardson 112 and the XLs fit perfectly, not too snug and not so loose the slide down your nose. I am a believer.
