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.

Product blocks cold and wind

This product blocks cold air. It is lightweight and zipper makes it easy to put on and off.

Warm and Reliable

The material is very warm without being too thick. Overall fit is good. The zipper isn't as strong as I would have liked so hopefully that doesn't become an issue down the road.

Men's UA Base 4.0 ¼ Zip

Great cold weather piece. The quarter zip allows for either a mock neck or can be unzipped for a more casual look or added coolness. This is a great cold weather piece for the active man.

Comfort from the Cold

This piece comes with After Burners to keep you warm in the winter. The UA Base 4.0 with its high neck styling goes above and beyond - it makes you feel like you sitting next to a roaring fire even when you facing the bitter cold. It is warm as wool but lightweight.

Sweet addition

It’s perfect for wearing zipped up or unzipped if it warms up I unzip and fold the tails to the side or if it gets too cold zip it up and helps with the neck breeze or cold
