I have been using these tights for all riding where temps fall under 60 degrees. They are very comfortable and well designed, and I am extremely happy with them.
This version has no pad, as I prefer to use cycling shorts underneath. Useful in the 20-40 F degree range, particularly when windy. Fleece insulation is warm but lighter weight. I use wool lightweight long underwear as more insulation between shorts and tights for temps from 0-20 F. Mine have just a thick drawstring, but I'd prefer an elastic waistband too. Not very stretchy and I feel them pulling down a little as I ride, so I stop occasionally to pull them up. If you're concerned about this, try the bib tight version. Fits snug at ankle zipper, good for adding booties, but limits me to a combo of a thin wool liner sock and mid-thickness wool hikingski sock.
