I've tried $300 bibs and these. Black bibs are my preference! They are the best.

I haven't had the opportunity to try them outside in colder weather but I definitely recommend getting the next size up from what you would normally wear.

The Ultimate thermal tights are my go-to winter bibs. The same chamois and pockets you love from the ultimate adventure bib shorts, just with warm coverage for your whole leg! Protect your knees, folks.
