Heat Holders® Men's Thermal Underwear will keep you warm on those cold winter days.
Choosing the perfect Heat Holders base layer
Consider both activity levels and temperature to determine which Heat Holders® base layer is right for you.
A light weight Heat Holders® base layer can be best in extreme cold if activity levels are high.
Likewise a heavier weight base layer can be best in milder temperatures if your activity levels are low.
Warm: Light weight warmth ideal for everyday cold.
X-Warm: Medium weight warmth ideal for very cold days.
