Jacket is very light and warm enough

Jacket is excellent well made very light yet warm enough. Also like the new zipper very easy to use

The zipper is mind blowing!

Yes, my favorite part of this jacket is the zipper. I never would have thought a simple zipper could blow my mind, but the fact that this one is magnetic, and gets the perfect connection every time is AMAZING. I hate trying to get my jacket zipped while having gloves on. This system eliminates that problem with the magnetic bottom, to make zipping the jacket a breeze. Besides this, the jacket does exactly what I need. It keeps my dry and warm in the snow. Could not be happier. It is the little details that make life enjoyable, and I appreciate the fact that Under Armour thinks about these little details in their material. Just another reason I go to Under Armour for new products and not their competitors. I am 5'10" tall and weight 200lbs. The Large fits me perfect.

Reactor Jacket review

Lightweight. Form fitting. Not bulky. Moves with you. Provides warmth but breathes. Only remaking question: Durability over long haul. [This review was collected as part of a promotion.]

Great portability

This jacket is very comfortable and nice to have on cold days. Zips into a pouch when not using it. [This review was collected as part of a promotion.]

Great jacket!

I loved this jacket, the waist area seems a touch small compared to the rest of the jacket which fit great and looked even better! [This review was collected as part of a promotion.]


I love it got it as a gift and really love it I would go for other colors [This review was collected as part of a promotion.]

Comfortable, light, slim fit

Super comfortable, even with a hoodie underneath. Love the slim look. [This review was collected as part of a promotion.]

Stays warm when wet

Ideal second layer under a shell; comparable or better than some of the high price down versions. Also suitable as a wear alone jacket [This review was collected as part of a promotion.]
