Extreme cold calls for extreme readiness. The Under Armour® Extreme Base Top for men delivers where other base layers fall short. 100% polyester with ultra-durable construction brings the warmest UA Base™ ever designed, to keep you comfortable even in the extreme chill of a cold treestand. A soft, brushed negative grid interior traps hot air to provide superior warmth, and ColdGear fiber enhancements promote body heat recirculation. Strategically placed 4-way stretch panels add stretch and dump excess heat, optimizing your heat generation. The signature UA Moisture Transport System wicks sweat and dries fast, while UA Scent Control technology inhibits the growth of odor-causing molecules to reduce your scent signature and level the playing field against game's natural advantage. Ordinary base layers can't come close to the warming power you'll find in the Under Armour Extreme Base Top. Machine wash. Imported. Manufacturer style #: 1297443.
