RAHwrote a review of Castelli Thermoflex Classic Leg Warmer on April 6, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
These are by far the best led warmers. I bought these to get through the fall to winter and winter to spring temps in MN and they've proven very effective. Great material to keep my legs just toasty enough for my rec rides and my work commute rides.
