Single-Use Waterproof Bib Prototype

I'm looking for a prototype of a single-use bib made from plastic. It should cater to toddlers, older children, and adults with special needs.

Essential design features include:
- Waterproof layer
- Adjustable neck size
- Catch pocket

Ideal skills and experience:
- Experience in product prototyping
- Knowledge of plastic materials and their properties
- Design experience for adjustable features

Looking forward to your creative solutions!
