arm and knee warmers got the nod in the October 2011 issue. "These comfortable, flexible warmers will keep you toasty on cool spring or fall mornings, but are so light you'll forget they're in your pockets after you've shed them for the day. Water-repellent nano fibers won't keep you dry in a downpour, but light drizzle beads on the surface, giving you a chance to seek shelter before the skies open."
NOTE: While the editors of Bicycling advise, "The fit is slightly large, so size down," the manufacturer recommends ordering arm and knee warmers in the same size as your Castelli jersey or Castelli shorts. For example, if you wear a Castelli jersey in size Medium, order Castelli arm warmers in size Medium; if you wear Castelli cycling shorts or bib shorts in size Large, order Castelli knee and/or leg warmers in size Large.
