These are comfy, convenient and warm while running* in the cold, and function sufficiently for limited back-and-forths outside. It works very well for what it is designed for: eg, playing soccer in the winter. It works poorly for prolonged cold spells with no vigorous activity: eg, walking along the National Mall in DC on a windy, winter night**. Reflective strip and key compartments are much appreciated functionality. Wish they would knock $5 bucks off the price since it does what it was made to do but doesn't go beyond that. Four stars.

* The packaging is labeled "RUNNING" alongside the UA logo.
** I have not tested it in wet, winter conditions yet.
