The shirt runs as an ultra-tight, second-skin compression fit; many customers find it fits as expected but sizing feedback is mixed, so check sizing charts and consider sizing up for a slightly less snug feel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does it handle sweat and temperature control?\u003c\/strong\u003e\u003cbr\u003eAnswer. The HeatGear fabric wicks moisture away and mesh panels at the underarm and back provide targeted ventilation, helping the wearer stay cool and dry during activity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this be used as an outer layer in cold weather?\u003c\/strong\u003e\u003cbr\u003eAnswer.
