Under Armour

Under Armour started with moisture-wicking compression shirts, and performance base layers remain at the core of the Baltimore brand's sportswear range. Its HeatGear line is designed for warm conditions and ColdGear for cold, alongside training tops, shorts, hoodies, sports bras and the Project Rock collection developed with Dwayne Johnson. The brand also makes running and training shoes, plus gear for team sports such as American football and basketball. Under Armour sells through its own stores and website, sports retailers and outlet stores. It suits gym-goers and athletes who prefer fitted, technical apparel, though many pieces use compression or fitted cuts that feel tight if chosen in the usual size. Buyers should check fit descriptors (compression, fitted or loose), compare fabric weights between HeatGear and ColdGear, and consider how synthetic fabrics handle odour with frequent use.
