Why We Like The Packaged Base 4.0 Legging

It's mid-December and the weather for the ice fishing trip is looking frigid. That doesn't mean it's time to bail though, we just put on the Packaged Base 4.0 baselayer legging step onto the ice with heads high. It's Under Armor's warmest baselayer yet, delivering proper insulation with comfort and confidence.

Enjoyable, tight, not super warm

These were not the warmest and were super tight compared to what I normally wear but I guess they worked for what I needed

This product really protects against extreme cold

The fit is great and it traps the heat without adding bulk. I wear it under my pants while going for a walk or running errands.

This product is excellent!!!

I work outside a lot servicing outdoor equipment. This thermal gear is awesome. I have ordered several sets of these. Keep you extremely warm without overheating yourself or sweating a lot.
