A protective wrap device for maintaining body temperature in a human user, the protective wrap device comprising:
- (a) a unitary member comprising:
- (i) a first sheet member portion having a height and a width, the first sheet member portion comprising a left portion on the left side of said width and a right portion on the right side of said width, and having a first edge at the left of said first sheet member portion and a second edge at the right of said first sheet member portion, wherein said first sheet member portion is thermally insulative;
- (ii) a second sheet member portion having a height and a width, said second sheet member portion comprising a left portion on the left side of said width and a right portion on the right side of said width, and having a first edge at the left of said second sheet member portion and a second edge at the right of said second sheet member portion, said second sheet member portion overlying at least a portion of said first sheet member portion,
- wherein said second sheet member portion is waterproof or water resistant, said first sheet member portion being connected to said second sheet member portion, said first sheet member portion and said second sheet member portion together forming a unitary insulative and waterproof or water resistant unitary member, said unitary member having a top edge and a top portion proximate said top edge, said unitary member having a bottom edge and a bottom portion proximate said bottom edge, said unitary member having a first edge and a second edge, and said unitary member having a front side defined by said second sheet member portion and a reverse side defined by said first sheet member portion;
- (b) a middle portion disposed between said top portion and said bottom portion, said unitary member defining first and second side edges extending in the direction from said top edge and said bottom edge, said bottom edge being substantially smaller than said top edge, said first side edge gradually tapering the width of the planar member in the direction toward said bottom edge, said second side edge extending substantially transverse to said top edge for a distance between 40 and 60% of the distance between said top edge and said bottom edge in a non-tapering fashion adjacent the top portion and a portion of the bottom portion, and said second side edge extending toward said bottom edge of said protective wrap device with an orientation which results in tapering the width of the protective wrap device in the region between the middle portion and the bottom of the bottom portion;
- (c) an elastic member, said elastic member having two ends, said elastic member being secured proximate each of its ends to the unitary member, said elastic member having an unstretched length and a stretched length, said elastic member being disposed proximate to said top edge of said unitary member, said elastic member being secured to said unitary member, and said elastic member extending along at least a portion of the length of said top edge of said unitary member, wherein the unstretched length of said elastic member is smaller than the length of the top edge of said unitary member, and wherein the elastic member, when stretched, overlies the top edge of the unitary member, whereby when the elastic member is unstretched, the top edge of the unitary member is gathered to have a reduced length substantially the same as the unstretched length of the elastic member, wherein the elastic member is secured to the unitary member in a manner that provides enough material to allow the elastic member to stretch, and when the elastic is stretched, the secured material unfolds to match the length of the elastic member;
- (d) a first connection member positioned on said unitary member and disposed on one of said sides of said unitary member, said first connection member in the area proximate the bottom edge of the unitary member comprising loop connection material that extends vertically along the first edge and is secured at points proximate the top edge and proximate a mid point, said mid point being between said top edge and said bottom edge of said unitary member, and wherein the first connection member is wider at the top edge than at the bottom edge, and wherein the first side edge has a tapered edge extending from the top edge to the bottom edge;
- (e) a second connection member positioned on said unitary member and disposed on an opposite side of said unitary member, wherein the second connection member extends vertically at least along that portion of the second edge proximate the bottom edge of the unitary member, wherein said second connection member comprises hook connection material.
