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.

My go to for cold weather
I work outside, and this 1/4 zip is my go to when the temp drops. I think I have 5 of them now... one for every day!

Best UA Base Yet
I've been a long time user of UA Base. This new technology is absolutely the best yet. Haven't gotten into really frigid temps yet but in High 20's and low 30's it was more than adequate.

Like the overall fit & feel
Purchased a Large. The fit & feel is nice. Only issue is it maybe a little too tight in forearms (if you like to roll-up your sleeves).

This product fit me perfectly!
I knew to order this product in a size Large because of their detailed description of the size and the height of the model in the photos, and it fit me perfectly! I wear this along with my black ColdGear Base Layer shirt underneath and the two products compliment each other perfectly. This performance of this 1/4 Zip was exactly what I needed for the cold weather we are experiencing in Canada. Highly recommend!

Great base layer.
Very breathable and great fit. Was hoping it would be a little bit warmer for extreme cold, however not disappointed with the purchase.

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.

I'm looking for a base layer for snowboarding. Is there a downside of buying the 4.0 rather than 3.0? Will 4.0 be too hot? Or is it that it doesn't allow for as much movement? Just looking for some guidance. Thanks.

what about 10-15 degree weather

Would you be able to swing a golf club in this

Does it shrink after being washed and dried? I’ve read that this runs a bit small and concerned it would be to tight afterwards.

Does it come with the leggings too or no
October 3, 2020
I don’t understand if this is like a base layer sweater or if you wear this over the long sleeve compression shirt. Will it be enough between 35-55 degree weather?

Does the 1/4 zip have a flap at the top of the neck covering the zipper as to not aggravate the neck?

Hi. Is it suitable for running outdoors in sub zero temp?
