When we need just a bit more warmth than a regular baselayer can provide, we add the Castelli Cold Days 2nd Long-Sleeve Baselayer to our winter kit. Built from recycled PET Polartec Alpha 90 fabric, this extra layer offers superior insulation, moisture management, and breathability to keep us comfortable when temperatures start to drop below freezing.
