The boys, aged 6-8 years, attend football festivals across the North-east and train regularly at the Newmachar Axis Centre.
Greenwell is an Aberdeen based company, based in East Tullos, which supplies modular buildings, containers, warehouse shelving and pallet racking and office furniture across the world.
It is a family run firm which at the present time employs 15 people.
Mark Turnbull, managing director of Greenwell, is a big supporter of the club, and his son Cal, age 6, has been playing with Newmachar United FC for over two years.
Mr Turnbull said: “I am delighted to help out Newmachar United FC.
“ It is a great, local club, which gives youngsters the chance to get some exercise, acquire new skills and learn how to work well in a team.
“Greenwell Equipment also supports Aberdeen Football Club’s Youth Academy, as we see football as an important local activity and also a great discipline and training ground for young people.”
Derek Reid, one of the coaches for the club, said: “We are really grateful for Mark and Greenwell for their support.
“We often attend football festivals and the other teams all look great in their kit, so we are thrilled to see our boys all now looking professional.
“It gives the players a real sense of pride and belonging.
“Newmachar United FC is an inclusive club, there are no try-outs, and we are open to every child of any ability, so we try to keep our costs to a minimum.
“Kit sponsorship is important as it makes the boys proud to belong to Newmachar United FC, and encourages them to try their best for the team.
“The cost of football strips, equipment and transport can add up, so we welcome all the support we can get.
“The boys are delighted with the new, warm track-suits which they are wearing with pride.”
