Frequently Asked Questions

What size bouffant cap should I order?
Keystone 111NWI-10 is available in 21", 24", and 28" sizes. The 21" fits most standard head sizes. The 24" and 28" sizes accommodate larger head sizes or longer hair that needs to be fully contained. When in doubt, size up — the elastic band provides a secure fit across a range of head sizes within each cap size.

What is the difference between the 111NWI-10 and other Keystone bouffant cap models?
The 111NWI-10 is a standard-weight (12 GSM) pleated polypropylene bouffant cap — the most economical option for general cleanroom, food service, and industrial use. Keystone also offers heavier-weight and specialty bouffant caps for higher-classification cleanrooms or applications requiring enhanced barrier properties. Contact MTE Solutions for guidance on selecting the right cap for your environment.

Are the 111NWI-10 caps suitable for cleanroom use?
Yes — the 111NWI-10 is produced by an automated manufacturing system with no human contact, making it suitable for cleanroom environments. The double-stitched, non-linting polypropylene construction is compatible with cleanroom gowning programs. Verify compatibility with your specific cleanroom classification and gowning protocol before use.

Why are multiple colors available?
Color-coded bouffant caps are commonly used in gowning programs to differentiate departments, access levels, visitor vs. employee status, or shift assignments — providing instant visual identification of personnel in controlled environments. The 111NWI-10 is available in white, blue, green, yellow, red, and orange to support color-coding programs.
