Under Armour ColdGear Reactor Women's Running Tights

These running tights feature ColdGear Reactor that actually adapts to what you're doing by dumping heat as you pick up speed.

The main feature that flows through the women's running tights is reactor technology. Reactor is a lightweight, intelligent insulation that adapts to your activity level for the right breathability and warmth for what you're doing. This innovative technology keeps you as warm as possible when there is little to no movement, but as soon as you get moving and the blood starts pumping, the technology works to dump that excess heat that is not needed anymore.

In addition, these running tights features a moisture management material that works endlessly to wick sweat and excess moisture as it's produced. Once wicked, the material transfers the moisture to the outer layers where it can be easily evaporated, ensuring you stay cool, dry and comfortable. A wide, flat waistband features an internal drawcord that offers the perfect stay-put fit, while free-cut cuffs feel super smooth and light next to the skin.

Furthermore, the tights offer superb storage spaces. An invisible zip side-seam pocket and expandable centre-front waistband pocket that is water resistant provide exceptional storage spaces for essential and valuable items. The front speedpocket fits most phones comfortably, up to 15cm x 8cm and reduces the bounce you get when carrying additional items. Lastly, the tights offer reflective details the enhance your visibility during low-light conditions, keeping you safe and seen when road running.
