THE official uniforms that volunteers and staff will wear at the Commonwealth Games this summer have been unveiled in a ceremony at the Emirates Arena in the east end of Glasgow.

Volunteers will wear a casual outfit consisting of a colour block polo shirt in red, white and grey, tracksuit bottoms and a matching soft shell jacket and cagoule, while technical staff will wear similar uniforms in cerulean blue and grey. Volunteers and staff will also be issued with a co-ordinating baseball cap, bag, umbrella and water bottle.

The uniforms were unveiled to assembled volunteers at an event hosted by sports presenter Hazel Irvine and radio presenter Des Clarke. Up to 18,000 volunteers, known as Clydesiders, are attending orientation events over the weekend.

The uniform reveal featured volunteers and Commonwealth Games mascot Clyde modelling the uniforms in front of a large crowd while the strains of the Pharrell Williams song Happy rang out throughout the arena.

Glasgow-based clothing company Trespass is responsible for designing and creating the outfits. Trespass, which originated in 1938 as Jacobs and Turner Limited, is now run by brothers Afzal and Akmal Khushi, who launched the Trespass brand in 1984.

Afzal Khushi said: "We wanted to create something which was both practical and stylish, would reflect the city and would help the Clydesiders and workforce stand out from the crowd."

Volunteers and staff will wear the uniforms throughout the Commonwealth Games, which runs from July 23 to August 3. Commonwealth Games Scotland chairman, Michael Cavanagh, said: "Seeing the Glasgow 2014 Clydesiders' uniform for the first time is another terrific step towards Scotland's biggest-ever sporting moment on the global stage becoming a reality.

"Those who wear it will be the friendly faces of the Games and offering a warm welcome to Glasgow and Scotland for the athletes of the Commonwealth and hundreds and thousands of fans who come here to enjoy one of the world's great sporting occasions."
