Thin-walled, high-strength prophylactic sheaths fabricated from elastomeric polymer materials are augmented along the border at the open end with a resilient material having a 100% tensile modulus substantially lower, preferably lower by at least about 75%, than that of the sheath material. This facilitates the rolling of the edge and stretching of the sheaths for purposes of application without compromising the high degree of sensitivity in terms of heat and sensation transmission associated with the thin-walled sheaths themselves.

A prophylactic device comprising a sheath of elastomeric sheet material having a 100% tensile modulus of at least about 200 psi and a thickness of less than about 0.0014 inch, said sheath having an open end and with a border containing a resilient material having a 100% tensile modulus substantially lower than that of said elastomeric sheet material, said resilient material being a member selected from the group consisting of polyurethanes, latex rubbers, silicone elastomers, foam silicone elastomers, ethylenepropylene thermoplastic elastomers, styrenic block thermoplastic elastomers, olefinic thermoplastic elastomers, polyether-block-amide thermoplastic elastomers, plasticized polyvinylchlorides, and acrylic-based thermoplastic elastomers, and the ratio of the thickness of said border to the thickness of said sheath being from about 10 to about 300.
