A North Yorkshire company is preparing to market what it claims is the world's first waterproof school blazer.
School Colours in Knaresborough has developed the "Ducksback" which has a special membrane between the fabric and the lining.
The company has been operating for more than 130 years and is now run by cousins Mark and Anthony Southcott.
Mark says it was his background as an industrial chemist that enabled him to develop the new blazer.
"Kids never like to wear a coat to school so they usually get wet," Mark Southcott continued.
"We have worked on the Duckback blazer with the single aim of keeping children dry on wet days."
The firm sells directly to schools and says there is already interest in the new blazer which will cost around £38.
