Steve K.wrote a review of Castelli Flanders Warm Long-Sleeve Baselayer - Men's on March 24, 2016
Familiarity: I've put it through the wringer
Fit: True to size
Very thin and light, but works incredibly well. My go-to setup for winter riding. On extra cold days, wearing a mesh summer layer underneath is a neat trick. This creates and extra layer of air pockets and improves the insulation considerably. I have washed it at least 20 times at this point and it's kept up really well. No tearing or piling of the soft inner layer at all.
