Why We Like The Packaged Base 4.0 1/4-Zip Top

When the mercury drops but the mountains are still calling, we're dressing as warm as we can without sacrificing breathability and lightness for our adventures in the most frigid of conditions. Under Armour's Packaged Base 4.0 1/4-Zip Top wicks sweat and dry quickly so we can plan for steep hikes without the risk of overheating. Stretch construction allows total mobility, and a quarter-length front zipper makes it easy to adjust when we warm up. Anti-odor treatment keeps us fresh after multiple days, and a brushed grid fabric traps air against our skin for maximum warmth.

  • Heavyweight baselayer for outdoor pursuits in frigid conditions
  • Brushed grid fabric traps air against your skin for maximum warmth
  • Material wicks sweat and dries quickly as you work up a sweat
  • Stretch construction lets you move freely on steep hikes
  • Quarter-length front zipper makes it easy to dump heat when needed
  • Anti-odor treatment keeps things fresh after multi-day missions

This product worked great! Not sure what the other person with 2 start was talking about.
The product kept me warm while skiing and I was hot at times , even with windy conditions and freezing conditions.
Th zipper worked great and it never got stuck. The material is light but very very comfortable.
It air dries very quickly and the you can tell it is a very well done product.
I highly recomend this product.

Four or five years ago I bought a ColdGear Base 2.0 with 1/4 zipper. LOVE it, still my favorite warm shirt, on its own or as a base layer. It's well made (premium spring-loaded zipper tab), soft, warm, with a waffle pattern interior. I wanted another one, but something warmer, so I purchased the 4.0 w/1/4 zipper.
When it arrived, I was so disappointed to see that the quality was not even close to the older 2.0. The zipper is cheap, the "feel" is cheap, and it's not as thick as my old 2.0!
Even at the sale price of $67.50 it's overpriced, at retail of $90, it's a complete ripoff. Needless to say, I'm returning it. I wouldn't buy it at $50. Shame on Under Armour.
This is the second "newer" Under Armour product that I have purchased that was sub-par. I think I'm done with Under Armour.

How to Measure:
For best results, take measurements over your underwear.
Place the tape measure under your arms at the fullest part of your chest, wrap around your body until your fingers meet and mark the measurement.
Measure around your natural waistline—right where your hips start. Be careful not to squeeze too tight to allow a little give.
With your feet together, measure around the fullest part of your hips to ensure you'll have enough room to move comfortably.
