These sterile hoods are made of a comfortable fabric that protects against various liquids and particulates. Each hood is individually packaged and sterilized to a 10?6 sterility assurance level (SAL) preventing workplace contamination and cross-contamination. The low-linting fabric helps reduce the release of unwanted particulates in your workspace. Hoods are designed with tunnelized elastic face providing a more secure closure and stronger seams. This also eliminates raw edges that can create and release additional particulates. Hoods include ties in the back to keep tie strings out of the way while you work.
