Abstract

A protective garment comprises a porous, breathable body portion and sleeves made of a nonwoven synthetic fabric. The sleeves and a front part of the body portion are covered at their outer surfaces by outer layers of plastic film. In one embodiment, a protective skirt of plastic film extends down below a lower edge of the body portion for covering parts of the wearer that extend below the body portion. The protective skirt can include perforations facilitating adjustment of a vertical extent of the skirt.

4. The protective garment of claim 1, wherein the body portion and sleeves are configured to cover the wearer'"'"'s arms and shoulders and to wrap around the torso so as to cover at least the front and sides of the torso.

5. The protective garment of claim 1, wherein the body portion is slit in back and includes a pair of cooperating fasteners attached to opposing edges of the body portion for securing the body portion about the body.

6. The protective garment of claim 1, further comprising a fastening arrangement attached at an upper end of the body portion for extending about the wearer'"'"'s neck.

7. The protective garment of claim 1, wherein the body portion comprises a nonwoven synthetic material.

8. The protective garment of claim 1, wherein the sleeve outer layers and body outer layers comprise polymer film.

9. The protective garment of claim 1, wherein the sleeves comprise a nonwoven synthetic material.

10. The protective garment of claim 1, wherein the body portion and sleeves comprise spun-bonded polypropylene.

11. The protective garment of claim 10, wherein the spun-bonded polypropylene has a basis weight of about 35 g/m².

12. The protective garment of claim 8, wherein the sleeve and body outer layers comprise polyethylene.

13. The protective garment of claim 1, wherein the body outer layer is generally rectangular having a width of about 50 to 80 cm and a length of about 60 to 90 cm.

14. The protective garment of claim 1, wherein the sleeve outer layers are generally unattached to the sleeves except at upper and lower ends of the sleeve outer layers.

15. The protective garment of claim 14, wherein the sleeve outer layers are stitched to the sleeves at the upper and lower ends of the sleeve outer layers.

16. The protective garment of claim 15, wherein the sleeves have cuffs that are elasticized.

17. A protective garment providing a barrier between a wearer and materials with which the wearer may come in contact, comprising:

a body portion configured to wrap at least partially about the wearer'"'"'s body;

a pair of sleeves attached to the body portion for receiving the wearer'"'"'s arms;

the body portion and sleeves being constructed of a layer of porous, breathable material;

a sleeve outer layer of polymer material disposed on an outer surface of at least a portion of each sleeve for enhancing the liquid-imperviousness of the sleeve and for preventing direct contact between the porous, breathable material of the sleeve and objects external thereto; and

a body outer layer of polymer material disposed on an outer surface of the body portion for enhancing the liquid-imperviousness of the body portion and for preventing direct contact between the porous, breathable material of the body portion and objects external thereto, the body outer layer being configured so as to cover less than the entire surface of the body portion; and

a protective skirt of polymer film extending down below a lower edge of the body portion for covering portions of the wearer'"'"'s body below the lower edge off the body portion.

18. The protective garment of claim 17, wherein the protective skirt is an integral extension of the body outer layer.

19. The protective garment of claim 17, wherein the protective skirt has at least one line of weakness extending horizontally therealong to enable a lower portion of the skirt to be torn off for adjusting a vertical extent of the skirt.

20. The protective garment of claim 17, wherein the protective skirt has a plurality of lines of weakness extending horizontally therealong and spaced vertically apart to enable a selectably sized lower portion of the skirt to be torn off for adjusting a vertical extent of the skirt.

21. A protective garment providing a barrier between a wearer and materials with which the wearer may come in contact, comprising:

a body portion comprising a breathable nonwoven synthetic fabric configured to wrap at least partially about the body of the wearer;

a pair of sleeves comprising a breathable nonwoven synthetic fabric and attached to the body portion for receiving the wearer'"'"'s arms;

a sleeve outer layer of polymer film covering at least a portion of an outer surface of each sleeve, each sleeve outer layer being attached to the sleeve over less than the entire surface of the sleeve outer layer; and

a body outer layer of polymer film disposed on an outer surface of a front portion of the body portion so as to cover less than the entire surface of the body portion, the body outer layer having a top edge, a bottom edge, and opposite side edges.

22. The protective garment of claim 21, further comprising a fastening arrangement attached to the body portion for looping about the wearer'"'"'s neck.

23. The protective garment of claim 22, wherein the body portion is slit in back and further comprising a pair of fasteners that are engageable with each other for securing the body portion about the body.
