While there is certainly a viable case for opting for a pair of the best winter bib tights, my preference is instead to use a pair of thermal bib shorts and a set of leg warmers. For me, it makes for a more versatile setup, especially in changeable conditions.
There's more to the best leg warmers though than just a pair of stretchy tubes. Fit is important, as are the grippers; not too tight that they are uncomfortable, but not so loose that they slip down embarrassingly. My preferences all come from a solid winter of testing in some incredibly bleak weather; wet, windy, and cold. Durability, wind resistance, DWR coatings, and fit were all put to the test and one pair was a clear winner.
