Matt J.wrote a review of Castelli Fondo Tights on November 9, 2011
Have used these tights on several rides over the past few weeks in temps between 35 and 45 degrees. They did a great job keeping warmth in and breathing. If they do get too warm, the zippers on the ankles allow you to pull them off without taking off your shoes. I'm 6'2'' and 182lbs with 33 inch waist and ordered XL. They fit very nicely over bib shorts.
