Children's organisations are calling for schools to switch formal uniforms in favour of clothing more suitable for play and physical activity to help children become more active.
Outdoor Play and Learning (Opal), a programme set up by former Bristol teacher Michael Follett, is behind the campaign and have joined with other groups who want to encourage always-active school uniforms.
Several schools across the south west of England have already adopted the idea and others are discussing the change.
PE lead at Summerhill Academy in Bristol, Sally Goodridge, said switching the uniform has made "children much more comfortable and we can jump up and get active at any time in the day".
