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.

Review Summary
Here's what customers have to say
The product is generally described as very warm, comfortable, and well-suited for cold weather activities. Customers highlight the warmth and insulating properties, stating it performs well as a base layer. However, some feel the new version is not as warm or wind-resistant as the previous generation, and a few noted a loose fit around the waist. Overall, the product is considered a high-quality, cold-weather base layer.

Very Good Product
If you play cold weather golf you really need to get the UA Cold Gear product. I like it because it’s flexible and fairly warm.

Under Armour - UA Base 4.0 The Best Warmth!
My Under Armour - UA Base 4.0 XL fits perfectly. The waiste band is comfortable. The fabric is a great barrier to the damp cold air near Lake Michigan as I watch my son’s Zion Benton High School’s Varsity baseball games.

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.

Which base layer would work for someone that works as security but is outside 95% of the time? Also I know it says from Florida but they get real cold easily. Esp at night around this time of year.
