Umbro is a British sports equipment manufacturer based in Cheadle. They specialise in football and rugby sportswear featuring their Double Diamond logo. Umbro products are marketed in over 100 countries.

The business was started by brothers Harold and Wallace Humphreys. The name is a portmanteau of um, from Humphreys, and bro from brothers.

Umbro currently focuses on football and rugby union equipment, with products such as kit (jerseys, shorts and socks), and boots, as well as manufacturing other clothing such as t-shirts and jackets.

Until the mid-1980s, the company manufactured only sports clothing, in particular football jerseys, shorts and socks, but had no footwear range. Eventually, in 1985, Umbro decided to introduce its first football boot into the Brazilian market. This design, cheaper than the products of existing boot brands such as Adidas, proved popular and went into mass production internationally two years later.

Umbro also manufactured a popular style of shorts that reached its peak in the United States in the late 1980s and early 1990s. They were made of nylon, had a drawstring waistband, and often came in bright colours. With the growth of youth soccer leagues in the U.S. in the 1980s, many youths, teens and young adults began wearing them as everyday clothing. At the height of the “Umbro fashion,” other brands of football shorts, such as Adidas, Diadora, Hummel, Lotto and Mitre, also became popular. Its major competitors in this market include Reebok, Nike, Adidas, Puma and Lotto.

Other releases by Umbro include the Stealth boot, released in 2010 and worn by players such as Gaël Clichy and Phil Jagielka. The same year, the company released the GT, worn by then-Fulham striker Darren Bent. The company announced it as its lightest ever boot. This was succeeded by the GT II model. June 2011 saw the release of the Umbro Geometra Pro. In 2013, Umbro introduced to a new wave of releases that included the Speciali IV and the Geometra II.

Following the purchase of the brand by Iconix Brand Group in 2013, the first major product release from Umbro was the UX-1, a technologically advanced football boot which was voted as one of the best new releases of the year
