shoulder resting portion 22 is designed to rest on the first shoulder , which is preferably located on the same side of the body of the wearer as the load 1 to be carried . also preferably , the shoulder resting portion 22 is detachably attached to each shoulder strap end portion 24 . preferably , the length of the shoulder strap 20 is adjustably extendible . ideally , as shown in fig1 an adjustment slide clip 39 permits adjustment of the effective length of each shoulder strap end portion 24 thereby providing adjustable extension of the shoulder strap 20 . the adjustment slide clip 39 is designed such that an end of a shoulder strap end portion 24 opposite a load attachment means 60 , 62 is looped around a buckle and back into contact with itself such that it is held from slipping by friction . preferably , the shoulder resting portion 22 is detachably attached to each shoulder strap end portion 24 . ideally , the adjustment slide clips 39 provide for the detachable attachment of the shoulder resting portion 22 to the shoulder strap end portions 24 . preferably , the shoulder resting portion 22 includes a pocket 25 . ideally , as shown in fig4 the shoulder resting portion upper surface 28 has a closeable opening 26 into the interior of the pocket 25 . even more ideally , the opening 26 is closeable with a zipper 27 . the shoulder resting portion lower surface 29 rests on the first shoulder of the wearer . ideally , as illustrated in fig5 the shoulder resting portion 22 consists of a strap 32 . coupled to the bottom of the strap 32 is a first layer 34 made of firm padding such as relatively hard foam rubber . coupled to the bottom of the first layer 34 is a second layer 36 made of soft padding such as relatively soft foam rubber . surrounding the strap 32 and first and second layers 34 , 36 is a covering 38 made of a durable material such as nylon . as seen in fig1 and 5 , a shoulder wrap member 70 is disposed around the shoulder resting portion 22 to provide additional padding . ideally , the shoulder wrap member 70 is detachably attached to the shoulder resting portion 22 by a fastener such as velcro or a zipper . the armpit strap 40 is designed to extend around the torso underneath the second shoulder of the wearer to assist in keeping the shoulder resting portion 22 from sliding off of the first shoulder of the wearer . the armpit strap 40 has an armpit resting portion 42 positioned between a pair of opposite armpit strap end portions 44 which are coupled to the shoulder resting portion 22 . preferably , the armpit resting portion 42 is detachably attached to one of the armpit strap end portions 44 . preferably , the armpit resting portion 42 has an inner surface 48 and an outer surface 49 . the inner surface 48 abuts against the torso of the wearer . preferably , the armpit resting portion 42 has a pocket 45 disposed within it . ideally , as shown in fig3 the armpit resting portion has an outer surface 49 with a closeable opening 46 into the armpit resting portion pocket 45 . even more ideally , the opening 46 is closeable with a zipper 47 . preferably , the length of the armpit strap 40 is adjustably extendible . ideally , the effective length of armpit strap end portion 44 is adjustably extendible , such as may be provided by means of an adjustment slide clip 39 . also preferably , as illustrated in fig4 the armpit strap end portions 44 are detachably attached to the shoulder resting portion upper surface 28 by a detachable fastening means 43 . for example , a hook and loop fastening means such as is sold under the trade name velcro may be employed as the fastening means . the waist strap 50 is designed to be extended around the waist of the wearer under the second shoulder to assist in keeping the load 1 close to the body of the wearer . the waist strap 50 includes a waist resting portion 52 positioned between a pair of opposite waist strap end portions 54 . each waist strap end portion 54 is coupled to a shoulder strap end portion 24 . preferably , the length of the waist strap 50 is adjustably extendible . ideally , each waist strap end portion 54 is mounted to the waist strap in a manner permitting the effective length of the end portion 54 to be extended or contracted according to the size of the wearer &# 39 ; s waist . also preferably , the waist resting portion 52 is detachably attached to each waist strap end portion 54 . adjustment slide clips 39 may be used to achieve both extendibility of the waist strap 50 and detachable attachment of the waist resting portion 52 to the waist strap end portions 54 . a first load attachment means 60 is coupled to a shoulder strap end portion 24 for attaching a load 1 to the shoulder strap end portion 24 . likewise , a second load attachment means 62 for attaching a load 1 to a shoulder strap end portion 24 is coupled to the other shoulder strap end portion 24 . ideally , as illustrated in fig1 the shoulder strap assembly 10 includes a bag 1 . the bag 1 is coupled to one shoulder strap end portion 24 by the first load attachment means 60 and to the other shoulder strap end portion 24 by the second load attachment means 62 . in such an embodiment , the bag 1 forms a portion of a loop of the shoulder strap 20 and also forms a portion of a loop of the waist strap 50 around the wearer &# 39 ; s body . in use , the shoulder strap resting portion 22 is placed over the first shoulder of the wearer . the armpit strap 40 is attached to the shoulder strap resting portion 22 and extended around the torso underneath the second shoulder of the wearer , with the armpit resting portion 42 beneath the underarm of the wearer . the waist strap 50 is attached to the shoulder strap end portions 24 and extended around the waist of the wearer under the second shoulder . a load 1 such as a bag 1 is attached to the first and second load attachment means 60 , 62 . as to a further discussion of the manner of usage and operation of the present invention , the same should be apparent from the above description . accordingly , no further discussion relating to the manner of usage and operation will be provided . with respect to the above description then , it is to be realized that the optimum dimensional relationships for the parts of the invention , to include variations in size , materials , shape , form , function and manner of operation , assembly and use , are deemed readily apparent and obvious to one skilled in the art , and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention . therefore , the foregoing is considered as illustrative only of the principles of the invention . further , since numerous modifications and changes will readily occur to those skilled in the art , it is not desired to limit the invention to the exact construction and operation shown and described , and accordingly , all suitable modifications and equivalents may be resorted to , falling within the scope of the invention .
