Adam Fullerwrote a review of Under Armour Coldgear Infrared Micro Jacket - Men's on July 20, 2016
Familiarity: I've used it several times
Fit: True to size
The Coldgear Infrared Micro jacket from Under Armour is a nice piece that can serve as an outer layer or a mid-layer under a shell depending on conditions and activity. I've found this piece to be comfortable walking around down to about 20F.
The fit is close, (41" chest) so it is not possible for me to wear more than one or two layers underneath this jacket. The Primaloft Silver insulation never feels bulky or bunches up on me. Overall the jacket moves with me very well.
The elastic cuffs are a nice touch. They feel comfortable against the skin, and they seal out cold without being constrictive.
The jacket packs into its stow pocket without too much trouble. It winds up being a cylinder slightly larger than what my cheapie North Face rain jacket packs down to. This is a good choice for travelers who need a warm piece they can pack in their carry-on.
My only real nitpick is that the pulls on the zippers could have been terminated with a plastic knob instead of being tied in a simple knot that can come undone. This is a pretty minor critique of another good piece that shows how far UA has come in the outdoor garment space.
