  • Indoor Comfort: In older buildings with poor insulation, thermals provide extra warmth without the need for heavy layers indoors.

1.3 Energy Savings

Wearing thermals at home can also help you save on heating costs. By staying warm in thermal layers, you can lower your thermostat and still feel comfortable, leading to reduced energy bills.
