How to Choose Thermal Underwear

Underwear Weight

You don’t have to overthink this, but you do need to consider both your metabolism and activity level. 

Here are your three basic weight options for long underwear:

• Lightweight: Moderate to cool temps.
• Midweight: Cold temps.
• Heavyweight: Below-freezing temps.

Our SubZero Thermal Underwear is consider Heavyweight underwear. NOOZ thermal underwear are designed for warmth with fleece lining interior as well as 4-Way stretch exterior lining. It is perfect for you to wear to exercise during winter.

Remember, too, that your base layer’s main job is moisture management. NOOZ's thermal baselayer uses breathable fabric, so it won't trap your sweat during workout. To be able to wick sweat efficiently, your next-to-skin layer needs to actually be next to your skin. So a comfortably snug fit everywhere is your goal. Some people prefer a loose fit in a warm-weather base layer. Their logic is that they’ll enjoy better air circulation and cooling. With a loose fit, though, you sacrifice wicking efficiency.
