Abstract
Abstract An extremely lightweight and highly flexible temperature protection suit shown as having a body portion, a hood, arm portions and leg portions is comprised of an inner layer of fabric in the form of a mat composed of non-directional fibers, preferably an artificial spun bonded olefin, covered on both sides by a thin, heat-reflective metallic layer. One metallic layer is shiny and the other dull and the suit is reversible in that it may be turned inside out to protect against heat or cold. Enlarged arm portions at the inner ends thereof facilitate the withdrawal of the wearers arms into the suit.

Total Claims: 14
Claim 1
Independent Claim
259 words
In a reversible temperature protection garment for the preservation and protection against heat and cold, the combination comprising: an upper body portion to cover at least the upper torso of the wearer, said upper body portion having arm portions to cover the arms of the wearer, a hood portion extending up from the body portion to cover the head of the wearer, said hood Portion having a front part covering a substantial portion of the face of the wearer and an elastic eye opening in the front part of the hood portion; said upper body, arm and hood portions being made of the same material, said material being comprised of a layer of a very lightweight TYVEK fabric having at least one side coated with a very thin layer of shiny, heat reflective metal and the material is dull on the side opposite the shiny layer to form a very thin, extremely lightweight, strong, soft, drapable composite whereby the shiny layer reflects heat back to the body of the wearer when worn inside for protection against cold and reflects heat away from the body of the wearer when worn outside for protection against heat, said upper body and hood portions being split down the front from the eye opening to the bottom of the upper body portion; and co-operating reversible releasable sealing fastening means extending along opposite marginal edges adjacent the split of the upper body and hood portions to seal the split closed all the way from the bottom of the body portion up to the eye opening.
