Quick Summary
The LAPASA Men’s Thermal Underwear Bottoms are fleece lined long johns leggings in white, size M, supplied as 2 bottoms in the lightweight option. They are part of a lightweight, midweight and heavyweight range, so the main choice is which weight suits the temperature you want to dress for.
