It's very warm but I could've done with a xxxl

I love this jacket very much it's nice and warm but an extra size up would've been nice (xxxl)

Does the job

Definitely does the job keeping me warm while running on cooler days. The collar/neck area is a little awkward, but I just keep it a bit unzipped, and it’s pretty comfortable. [This review was collected as part of a promotion.]

Has not held together

I am a big Under Armour, most of what I own is UA clothing and gear. I liked this vest until the hem started to unravel within the first month of use. I was shocked because normally their clothing holds up very well and tend to last for several seasons. Not sure what to think now.

So far so good!

I am a Mailman and as you know we deliver mail no matter if it snows, sleets, rains, or face with killer heat in summer. When I found this vest it was perfect to what I wanted. I needed something lightweight that I can wear under my Postal jacket that’ll keep me warm during winter. I live in Maryland so it’s not too bad here but thre weather does get a little bad. I love everything about this jacket and would buy it again. I wear it almost every day to work and it’s held up really well.
