fig1 a is a side perceptive view of a male underwear brief 100 , according to an embodiment of the present invention . male underwear brief 100 comprises an elastic waistband 101 attached to the upper periphery of the brief 100 , cloth material joined circumferentially to waistband 101 which forms a back panel 106 , an upper front panel 104 , and a crotch panel 105 proceeding from a lower region of the back panel 106 to the front and upward , a first and a second opening 102 for a person &# 39 ; s legs and a horizontally oriented and aligned fly opening 103 . the edges of the first and the second openings 102 for the person &# 39 ; s legs are reinforced in most embodiments , and in most cases the reinforced edges are of elastic material . in one embodiment horizontally oriented and aligned fly opening 103 is positioned low in the front of brief 100 . back panel 106 and crotch panel 105 are joined to reinforced edges of the leg openings 102 . the upper front panel is joined to the reinforced edges of leg openings 102 as well , and ends at a horizontal elastic band 108 attached continuously to upper front panel 104 . horizontal elastic band 108 is attached to each of the reinforced edges of leg openings 102 . in one embodiment the upper extent of the material of crotch panel 105 is at line 110 . this creates an overlapped fly opening 103 open from below upward into the brief , of a vertical dimension “ d ”. this dimension may vary depending on the placement of both the upper end of the crotch panel , and the lower end of the upper front panel . fig1 b is cross - section through horizontal fly 103 of fig1 a taken along section line 1 b - 1 b into the brief . in this particular embodiment there is elastic band 108 overlying the upward - extending crotch panel material 105 , but there is no band on the upper edge of crotch panel 105 , which ends at line 110 ( see fig1 a ). in some cases this edge may be hemmed . again , the placement and attachment of the crotch panel material and the upper panel material determine dimension “ d ”, which may vary accordingly . the embodiment represented by fig1 b may be considered a “ one - band ” embodiment . in yet another embodiment upper front panel 104 may end without an elastic band , at an edge that may be , for example , hemmed as well , and this particular embodiment may be considered a “ no band ” embodiment , but nevertheless creates an upwardly opening overlapped horizontal fly opening of dimension “ d ”. fig1 c illustrates the cross - section of the fly panel in another embodiment , wherein another elastic band 107 is added at the upper edge of the crotch panel . the elastic bands may be of equal height and weight , or different , and the overlap may be variously managed as described above . the embodiment represented by fig1 c may be considered a “ two - band ” embodiment . at least one other two - band embodiment is described additionally below . fig2 is a side perceptive view of male underwear brief 100 illustrating another embodiment of a “ two - band ” brief , wherein a front pouch is also provided , not shown in the embodiments of fig1 a , 1 b and 1 c . to better illustrate how a pouch is formed with the upper front panel , the upper front panel in shown in an open position in subsequent stages of assembly in fig2 , 3 , 4 and 5 , according to an embodiment of the present invention . crotch panel 105 proceeds upward from a lower region of back panel 106 to the front and ends at a first horizontal elastic band 107 joined securely to each of first and second leg openings 102 , as shown in fig1 c . at this stage of assembly edges of upper front panel 104 are stitched to the elastic leg bands 102 down to point ( a ) as shown in fig2 . note that point ( a ) is repeated on the opposite leg opening , although not seen in fig2 . the bottom edge of upper front panel 104 ends at and is joined to a second horizontal elastic band 108 as shown in fig2 . fig3 is a side perceptive view of male underwear brief 100 , illustrating the upper front panel in a fixed condition , according to an embodiment of the present invention . one side of upper front panel 104 is joined to the leg openings on both sides at two different points ( a ), ( b ) to form an extended loop as shown in fig3 . the opposite edges of horizontal elastic band 108 are stitched respectively to the reinforced edges of leg openings 102 at the opposite sides , and are positioned in one embodiment below the position of band 107 , as seen in fig1 c . this is optional placement in different embodiments , and the position of band 108 may vary , affecting the dimension “ d ”, fig1 b and 1 c . further , the edges of the upper front panel are stitched to the reinforced edges of the leg openings as shown , down to the horizontal fly . first horizontal elastic band 107 and second horizontal elastic band 108 are only stitched to the edges of the leg openings 102 , leaving an opening up from the bottom of the horizontal fly to the inside of the brief . fig4 is a cross sectional view of the male underwear brief , essentially the same as fig1 c , illustrating the arrangement of the two horizontal elastic bands in this example . the bands are only stitched to the elastic leg bands 102 . this leaves an opening up from the bottom of the fly to the inside of the upper front panel as shown in fig4 . fig5 is a side perceptive view of male underwear brief 100 , illustrating the placement of a third horizontal elastic band 109 , according to an embodiment . the upper front panel is folded , as shown in fig3 , with point ( a ) and point ( b ) relatively close together in this example , on both leg openings as shown . third horizontal elastic band 109 is joined only to each of the reinforced edges of the leg openings 102 over the upper front panel 104 just above and parallel to second horizontal elastic band 108 . the position of band 109 is below the attachment points ( b ) intentionally to provide support in use , as the pouch is intended to support a user &# 39 ; s organ or organs . third horizontal elastic band 109 is stitched above second horizontal elastic band 108 and below attachment points ( b ) to each of the reinforced edges of the leg openings 102 , but not to the upper front panel 104 or anywhere else . since the third horizontal elastic band 109 is stitched only to the reinforced edges of the leg openings 102 , it can be pulled outward . in alternative embodiments points ( b ) may be positioned on the edges of the leg openings further below points ( a ), providing a greater opening from inside into the pouch that is formed by the folded material , or the third horizontal elastic band 109 may be stitched continuously across the front panel . fig6 is a cross sectional view of the male underwear brief illustrating the arrangement of the three horizontal elastic bands in this example . crotch panel 105 proceeds upwardly from a lower region of the back panel to the front and ends at first horizontal elastic band 107 attached continuously to the crotch panel and to each of the reinforced edges of the leg openings . upper front panel 104 is joined to the reinforced edges of the leg openings and ends at horizontal elastic band 108 attached continuously to the upper front panel . band 108 is attached to each of the reinforced edges of leg openings typically at some distance below band 107 . this leaves an opening up from the bottom of the horizontal fly to the inside of the upper front panel 104 as shown in fig6 . in alternative embodiments the position of band 108 may be varied from directly over band 107 to substantially below band 107 , varying the vertical dimension of the upwardly - extending opening into the brief . band 109 is stitched above and parallel to band 108 to each of the reinforced edges of the leg openings at a distance that may vary , but is typically placed to support the pouch developed as shown in fig5 . fig7 is a side perceptive view of male underwear brief 100 with the fold of the upper front panel in a closed position . the extended loop of upper front panel 104 , as illustrated in fig3 and 5 , has been folded downward . the folded loop is brought down , and the top edge of the loop comes right to the bottom edge of horizontal elastic band 108 at line 111 . the side edges of the loop are stitched along the reinforced edges of the leg openings down to the horizontal fly thereby forming a pouch from within the brief along a horizontal line from points ( a ) and ( b ) on each leg opening . the relative positions of bands 107 , 108 and 109 are shown now in fig7 as dotted lines , because they are behind the folded down pouch material . it should be noted that the extent of material 104 may be adjusted , depending on a chosen distance between points ( a ) and ( b ), which define an opening size into an internal pouch , to provide the proper placement of edge 111 . in still another embodiment of the invention a front pouch may be formed by fabric cut , rather than by folding the fabric of the upper front panel as described in detail above . fig8 a is a perspective view of the brief showing horizontal elastic bands 107 , 108 and 109 . in this embodiment upper panel 104 is cut to provide a width w 1 across points ( a ) to establish a dimension across the front of the brief , and another width w 2 across points ( b ) below point ( a ) for the same purpose . w 1 and w 2 will typically be not the same , but w 1 greater than w 2 . fig8 b illustrates an exemplary cut for upper front panel material 104 with points ( a ) and ( b ) and widths w 1 and w 2 . the edges are curved outwardly as shown between points ( a ) and ( b ). it is essential that the distance along the curve of the cut fabric from points ( a ) and ( b ) on each side be the same distance as between ( a ) and ( b ) on each leg band of the brief . this way , when the fabric is sewn to the leg bands on each side an outwardly - extending pouch may be formed . this pouch in use supporting a user &# 39 ; s organ or organs will tend to form outwardly and downward as well . horizontal fly 103 can be stretched more than 25 % to let the penis and scrotum , or just the scrotum out and to provide a slack - line - type closure for a supportive upper pouch ( i . e . for upper front panel ) 103 to hold the penis , or the penis and scrotum . horizontal fly 103 creates a comfortable collar close to the user &# 39 ; s torso and the second horizontal elastic band , like a full - width fabric eyebrow , shrouds 1 ″- 2 ″ of the exposed organ , when the organ is pulled out . the first , second and third horizontal elastic bands may have a width of ½ ″- ⅝ ″ and are wrapped up for comfort in the brief 100 . in one embodiment , the male underwear brief in this example provides various options for the person to provide a continuous comfortable wearing for 24 hours every day . in one option the pouch formed of the extra material of the upper front panel covers and lifts both the penis and the scrotum , while slit - aperture horizontal fly 103 closes under the overhanging weight of the penis with the scrotum under . the pouch formed with the extended loop of the extra material of the upper front panel absorbs urine , reduces rolling and squeezing of organs between thighs and looks similar to jocks / briefs worn worldwide . in a second option the pouch covers and lifts only the penis up , or to one side while a slit - aperture ( horizontal fly ) 103 collars the scrotum . the scrotum may extend outside the brief which may be suitable for wear with most outerwear and in high humidity . in a third option horizontal fly 103 of the male underwear brief may let the penis out and collar the penis and the scrotum . the horizontal fly 103 further covers the pubic hair . the organs ( penis and scrotum ) may be pulled out and the buttocks region will stay covered without doffing the brief 100 . the horizontal fly 103 creates a comfortable collar close to the user &# 39 ; s torso , and the second horizontal elastic band 108 acts like a full - width fabric eyebrow , to shroud 1 ″- 2 ″ of the exposed organ . it will be apparent to a skilled artisan that the embodiments described above are exemplary only , and that there may be many alterations made in these examples without departing from the spirit and scope of the invention .
an underwear brief has a waistband , cloth construction forming a front region , a back region , side regions and a crotch region , two leg openings , a horizontal fly implemented with a first panel overlapping outside a second panel , with ends of each of the two panels secure to the fabric of the front region such that the horizontal fly provides a horizontal vertically - oriented entrance or exit through the front region of the brief , a first elastic band joined continuously , end - to - end , along full length of a lower edge of the first panel , a second elastic band joined continuously , end - to - end , along full length of an upper edge of the second panel , and a third elastic band joined horizontally to the front region at a position above and parallel to the upper edge of the second panel , with only the opposite ends of the third elastic band joined to the front region .
