     FIELD OF INVENTION 
     The present invention related in general to collapsible cubicle devices providing privacy while changing clothes outdoors and in public. This invention lies in the field of portable enclosures for changing clothes and directed to such device which may be opened and closed quickly for storage and transportation. It is more particularly directed to portable changing tent which may be opened/closed very quickly with no need for special skills or manual dexterity and which is sufficiently rigid for general use in public. 
     BACKGROUND OF INVENTION 
     Many of the portable changing enclosures invented are open on the bottom and have a plurality of members which must be secured together with many fasteners requiring more time and dexterity to assemble. They provide limited privacy, are impractical, and offer no protection from the debris and rugged terrain that will damage suits worn in association with cold water activities. 
     BRIEF SUMMARY OF INVENTION 
     The principal objective of the invention to provide a wearable enclosure that provides privacy while changing in to and out of suits worn in association with cold water activities. 
     Another objective is to provide a stable and protective surface to change upon preventing damage and soiling of suits. 
     It is also an objective of the present invention that it interact with the users physical movements required to disrobe from suits worn in association with cold water activities. 
     A further objective of the invention is that it be made in the US and that it be partially comprised of recycled materials. 
     Still a further objective is to provide such a device in non see thru, lightweight textile, easy to use, and easily stored in devices such as but not limited to backpacks and duffle bags. 
     From forgoing general description of the invention achieves, as an important objective, said invention is made in a range of sizes for both sexes each size large enough to allow the user to change freely and safely. 
     The forgoing objects can be accomplished by providing a device that combines a half length trapezoidal, non see thru, light weight textile comprised of two side panels, a front panel, a rear panel, stitched together, and a durable material along the bottom of the enclosure wall minimizing damage. The top portion has an opening with a draw cord waist that rests upon the hips when tightened. Once the user is standing upon the flexible rubber base the enclosure wall is easily pulled up and over the users hips. Two openings located on either side of the enclosure wall from the upper thigh down below the knee allow the user to disrobe and exchange clothing, a privacy flap open on one side attached by a hook and loop fastener covers the opening on the inside, a transparent vinyl window just below the knees provides additional safety and control when changing. The bottom of the enclosure wall is adhered to a flexible rubber base enclosing the user from the waist down. The bottom of the flexible rubber base is textured adding traction, the top of the flexible rubber base has a 5 mil. thick textured neoprene matt protecting suits from damage and providing additional traction and comfort when changing. The flexible rubber base interacts with the users physical movements required to disrobe.

     DETAILED DESCRIPTION OF INVENTION 
     The following detailed description represents the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principals of the invention. 
     Referring to  FIG. 1 , an enclosure ( 1 ) that may be portable and easily used may be of generally trapezoidal form having a wall ( 2 ), an open top ( 3 ), and an enclosed flexible rubber base ( 4 ). The wall ( 2 ) may be made of lightweight, non see through textile cut into four panels; a front and back ( 5 ), and two sides ( 6 ) sewn ( 7 ). All four panels ( 5 , 6 ) taper at the top forming an opening ( 3 ) for the waist. 
     As shown in FIG.  1 , 3 , 4  there may be a draw cord waist that when tightened allows the enclosure to rest upon the users hips. 
     There may be openings ( 11 ) cut and hemmed down the center of each side panel ( 6 ) as shown in FIGS.  1 , 3 , and  4  from the upper thigh down below the knee. On the inside of the enclosure wall over the opening ( 11 ) may be a privacy flap ( 12 ) which may be sewn to a wall on three sides and which may be open down the side ( 13 ) facing the front of the enclosure wall that may be closed by a hook and loop fastener ( 14 ). 
     As shown in FIGS.  1 , 5 , there may be a transparent vinyl window ( 9 ) positioned below the knees across the front wall which may be sewn ( 7 ). 
     As shown in  FIG. 5 , there may be a stretchable material ( 8 ) below a vinyl window ( 9 ) that may transition into a durable material at the bottom of the enclosure wall ( 22 ) which is enclosed by a flexible rubber base ( 4 ) with a textured bottom ( 23 ) which may be attached to the enclosure wall by high strength adhesive. Upon the top of the flexible rubber base ( 4 ) may be a 5 millimeter thick rubber neoprene textured matt ( 25 ) which may be adhered to the flexible rubber base. As shown in  FIG. 5 , there may be a two inch wide rubber channel ( 26 ) adhered along the perimeter of an interior edge between the bottom of the enclosure wall ( 22 ) and a neoprene rubber matt ( 25 ) which may include a weep hole ( 27 ) in one corner. 
     Referring to  FIG. 2 , the embodiment of invention ( 1 ) which may be of generally trapezoidal form having a wall ( 2 ), an open top ( 3 ), and a closed base ( 4 ) as shown in  FIG. 1  which may be enclosed by a flexible rubber base ( 4 ) with a textured bottom ( 23 ) having a 5 millimeter thick textured neoprene rubber matt ( 25 ) upon the inside as shown in  FIG. 5  interacts ( 28 ) with the users physical movements ( 29   a , 29   b ,  29   c ) required to disrobe.
