Respirator harness assembly

Disposable adherent collars based on low cost supple sheets carrying a low-adherency pressure sensitive adhesive are disclosed. The adherent collars of the present invention are significantly more comfortable to wear than prior art adherent collars due to the suppleness of the sheet used in the collars, and to the low-adherency character of the PSA, achieved preferably through the use of a discontinuous layer of PSA material. Because of the suppleness of the sheet the low-adherency adhesive is effective to hold the sheet in place.
