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.

Great Warmth for outdoor activities

My son loves these because he works outside for a crane service. They keep him warm on cold days and they are very comfortable.

Best base layer

By far the best base layer out there. Thin enough to where you don't feel like the Michelin man yet keep you warm. Absolutely love them. Don't let the price scare you. Well worth it.

under Armour cold gear.

I bought this under Armour cold gear not knowing if I was going to like it. I am a captain on a sport Fish boat. I stand in the cold all day long. Best money I ever spent. Ilove them.

Last Gen was better

Last gen base 3.0 feel thicker and probably same amount of warmth. Just giving my real world experience using these daily. Purchased the 4.0 in end of 2024, thinking they would be warmer and ticker than last Gen 3.0. I was wrong. Waffle weave of what ever you call it, it is tiny compared to the 3.0. Maybe not important.

Well made

Purchased for tactical operations. Well made product with great heat retention. Used during cold weather operations and these extended the operational time of individuals, making relief operations an easier task. May be too warm in an active environment.
