I have a pair of the of the Mid Zero tights and another pair of Canari tights that are a bit heavier. They replaced my beloved Hind tights that I had for 9 years and finally ripped last winter. Neither are padded; I have no issue wearing 2 layers. I also have a pair of Ibex wool/wind resistant tights that I use for x country skiing and occasionally for riding.They are super warm. I bought a pair of Gore padded tights from Bluetree last year; ow! The chamois and seams hurt me so badly, I threw them out.
I have a Gore jacket that is super warm, but I also wear my regular wind jacket over thermal tops. Then there are the 3 jackets I wear xc country skiing. A Go-Lite, which is super warm, a newer Ibex jacket which is more breathable, and something that is more of a shell that DH just bought me, on line. I've worn the Go Lite and the Ibex ones riding, but they are super warm. I don't ride in the dead of winter, unless the roads are clear and it's at least 35 degrees or so. I'd rather be on the x country ski trails.
