Know Your Under Armour: UA RUSH


UA RUSH™ is Under Armour’s line of performance apparel that’s designed to be worn, as Under Armour says, ‘at the time of sweat.’ It’s a collection that features both men’s and women’s apparel, including tops, bottoms, bras, shorts, leggings, and jackets. Under Armour also incorporates various technologies into the UA RUSH™ collection.

What Technologies Does UA RUSH Use?

All UA RUSH™ gear features CELLIANT® bioceramic infrared technology. CELLIANT works by absorbing and converting body heat from the wearer into full spectrum infrared energy. This is clinically demonstrated to temporarily increase local circulation, improve cellular oxygenation and improve strength, stamina and endurance. The infrared advantage provided by CELLIANT helps Under Armour, through the UA RUSH™ collection, fulfill its promise of optimizing human performance. Other technologies that are found in some UA RUSH™ pieces are:

  • Under Armour ColdGear®
  • Under Armour HeatGear®
  • Under Armour SmartForm

Each technology has distinct functional properties.

What is ColdGear®?

Under Armour’s ColdGear® is designed to keep your core temperature warm while training in the cold.1 It’s a lightweight fabric that sits next-to-skin. The back of the fabric features channeling that helps trap heat while still being breathable. Additional features of ColdGear include 4-way stretch, active odor control, and quick drying fabric.

What is HeatGear®?

HeatGear® is Under Armour’s solution to keep you cool while training in warm conditions. The fabric is designed to be very lightweight, and to wick sweat away from the skin and diffuse it through the material so it can evaporate more quickly. The fabric is also highly breathable, perfect for hot days.

What is SmartForm?

Under Armour’s SmartForm is uniquely constructed to flex to your shape as you move. The customized fit and unmatched comfort and mobility of SmartForm is ideal for applications such as sports bras and performance leggings.
