Pearl Izumi is usually my first choice in bibs and warmers and I am very happy with my thermal leg warmers.
They stay in place and keep out the cold and I live in north Minnesota! They do wrinkle behind the knee slightly although that's no big deal so I give a 4 star rating.
Been riding for 30 years, with either knee warmers, knickers andor tights. I hate riding tights, as their too restrictive. These are really comfortable and very warm too. Probably too warm for me in anything above 47 F. Havent found a temp their not warm enough in, I dont usually road ride under 25 F. Love these!
Super warm when cold.
The only reason I gave it 4 stars because it bunches a little behind my knees.
Love my new leg warmers. Easy on off they do the trick.
