Protective trousers with an integral urination tube - involving a one way outlet, used for hazardous environments

摘要

The integrity of protective trousers for men in a hazardous environment is protected when urinating by an internal sheath having a drain tube leading down a trouser leg to an outlet protected by a suitable non-return valve or baffle. The tube may be confined by a local double walled seam. No specific materials are quoted, except for incidental use of hooked fabric fasteners (RTM-"VELCRO") to secure the bottoms of the trouser legs as a close fit.
