London school joins always active uniform pilot to combat children’s inactivity and obesity levels 

Active Uniform Alliance founding partner the Youth Sport Trust has launched an exciting year-long initiative with Harbinger Primary School in London, to demonstrate how reimagining school uniforms could be key to tackling the nation’s growing inactivity crisis among children. In partnership with Sports Direct, every child starting Reception for the 2025/26 academic year at Harbinger Primary School has received an Always Active Uniform, gifted by Under Armour, to wear in place of the school’s traditional uniform.  

The Always Active Uniform is a flexible, comfortable school uniform including active footwear, designed to support spontaneous movement and daily activity throughout the school day. To understand the impact of this change, pupils will also be wearing donated Moki Bands, as part of a live research project capturing real-time data on how much children move during the school day following this change in uniform. The pilot offers a unique opportunity to see how a simple change in what children wear could spark greater activity and healthier habits.
