This medium-weight undershirt is designed for use in cold weather or intense cold conditions when moisture transfer is a top priority. The hydrophilic Prosecco treatment distributes the moisture over a wider surface and accelerates evaporation. Castelli uses two different thicknesses of materials. The thinner fabric is used where the undershirt is covered by pants or straps and therefore less insulation is needed at these locations.
