Reusable hat in theatre

Dear all, 

Any advice would be greatly received! 

I have been searching for a grant application to apply for  / funding application  / industry funding to provide all surgical trainees in the North west with 4 reusable hats with their name on. A recent questionnaire study we completed showed registrar willingness to wear reusable hats and how this would have a positive impact on their wellbeing and sustainability. 

If anyone knows of such funding available please share below.
