Dude,

I've worn these tights for 5 seasons with great results.

I have 2 pairs of the heavier weight 100's and 1 pair of the thinner. You can double them up easily. The thinner ones are more of a slick outer to go well as an under layer. Honestly though I have almost never doubled them up. Worn them below freezing.
