Under Armour Heat Geat Mock Neck Long Sleeve T-Shirt^BOY Underwear|Thermals

HeatGear® is our original performance baselayer—the one you put on first and take off last. So we made it extra comfortable by wicking sweat and stretching so you can move no matter what. HeatGear fabric is ultra-soft smooth for extreme comfort with very little weight. 4-way stretch material moves better in every direction. Material wicks sweat & dries really fast. Mock neck construction for added coverage. Heat Gear fabric is ultra-soft smooth for extreme comfort with very little weight4-way stretch material moves better in every direction.
