In another contemplated embodiment, the loops are defined by a continuous ribbon affixed to the cape at spaced intervals defining the ends of the loops.

Abstract: Cold weather, especially when combined with wind and moisture, can cause significant health problems. In practice it will limit productivity and a normal human's activity. The bad effects will be even worse in people who have cardio-respiratory problems. Therefore, this applicant introduces a unit that will prevent such exposure and its related problems. These hats will be made from combinations of an outer and an inner cover. The inner cover is a soft lining and the outer cover is a protective cover that will stand over the first cover. The outer layer will be non-permeable and will not allow air or moisture to move in. This unit will be further fortified by a brim, shield, filter and means that will allow the motion of the air inside the nose-mouth area to be controlled. The unit may also have a tubing to allow oxygen or another treated gas to come in. These units may also have other pieces such as microphones and speakers in order to allow communication to be facilitated in difficult circumstances.

Therefore, the face mask is relatively inelastic, while permitting elastic fit around the face.

Abstract: The invention comprises a unitized system of garments that prevents particulate matter from passing from the body of the person wearing the garments into the surrounding atmosphere or vice versa. Water vapor or other gases such as air are free to pass through the garment fabric which is a laminate of expanded, porous and gas permeable polytetrafluoroethylene (PTFE) bonded to a porous and gas permeable backing material. Particulate matter is blocked by the very fine pores of the garment. The person is totally enclosed in the garments preferably presenting virtually a 100% external surface of nonlinting PTFE, and passage of water vapor or water vapor and air through the laminate is sufficient to allow breathability. In order to make practical putting the garment on and taking it off, and to eliminate gaps in the garment, separate pieces are required and particulate-proof barriers are required where the separate sections are joined.

Abstract: Form-fitting, comfortable, soft-shell protective apparel, commonly called a as mask, for protecting the head, upper body and respiratory tract from chemical/biological agents and toxins and radioactive particles. A unitary, easy-to-put-on, heat and moisture-dissipating multi-layer construction enables prolonged use and internalizes an adjustable suspension system as well as the purified breathing-air path. The latter is structured to enable the self-contained purifying agent to be located away from the face for facilitating weapons compatibility and reducing fatigue. Goggle-like eye lensing is designed to minimize eye relief and maximize peripheral vision and look-down capability, while providing optical correction and laser-light protection. The mask design minimizes dead space leading to distortion and other communications problems, and enables purifying-agent changes in a "hot" environment.
