Pearl Izumi has three weather categories for their cycling tights: Cool, Cold, and Deep Cold. The Expedition Thermal Cycling Bib Tights fall into the Cold category.

QUESTION: What does “no-drop ride” mean? My bike shop has a list of group rides, and they describe some of them that way in parentheses. —Jeff T.

Cold weather is associated with an increased incidence of heart attacks (Arch Intern Med, 2004;164(8):863-870).

Even a short-term drop in air temperature in the tropics is associated with increased heart attack risk. Read more.
