Under Armour started with one complaint: a cotton training top that soaks up sweat and stays heavy for the rest of the session. Everything the brand sells still traces back to that idea, and the fabric names on the label are the fastest way to understand what you are actually buying.

The fabric names, decoded

HeatGear is the warm-weather family, built from thin smooth-faced knits that move moisture off the skin instead of holding it. ColdGear works the other way round: a dual-layer construction with a brushed inner face that traps warmth while the outer face sheds damp. Iso-Chill yarns are engineered to spread body heat across a wider surface, so the fabric reads cool the moment it touches you. Vanish is the current flagship training range, cut light and stretchy for people who train hard rather than pose in the mirror.

Shoes, and the sizing question

HOVR is the cushioning platform underneath most of the running line, aimed at returning some energy rather than simply absorbing impact. Training shoes sit lower and flatter for lifting and lateral work, so a running pair is a poor substitute in the gym. The one thing worth knowing before you order: Under Armour lasts tend to run on the narrow side, and buyers with wide feet often size up rather than take their usual number.

Football, golf and court sport

The Magnetico boot line is the football flagship, sold in several soleplate versions for firm ground, artificial grass and indoor surfaces, which matters more than the colourway. Golf polos and mid-layers use the same moisture-management fabrics as the training kit. Basketball is anchored by the long-running Curry signature line, which has its own following well beyond the court.

Before you press pay on the UK site

The promotional code box sits on the basket page, not the payment step, so apply it before you move on. Codes on sportswear sites are commonly restricted to full-price stock and exclude already-reduced lines, so check the total changes before you confirm. Sizing charts sit on each product page and are worth reading rather than guessing, because a compression fit and a loose fit in the same size are very different garments.
