ColdGear Reactor active insulation adapts and reacts to any level of cold to keep you warm. The wavy, stretchy fibers create an unbroken pattern for reliable, even warmth without gaps or variances in loft. The fibers buffer the extremes of activity to provide warmth over a wide comfort range. They're also water-resistant and moisture-wicking for absolute comfort.
Versatile warmth, but there's more…
The windproof construction also keeps you warm by shutting out the cold breeze. UA Storm water resistance helps keep you dry if you get caught in some drops or flakes. There are even added convenience features…the MagZip zipper has a magnetic closure to make zips a snap. And the Jacket is packable for ultimate portability.
When the cold level changes, you stay warm in this Under Armour® Jacket.
