Abstract: A shoulder strap has upper and lower outer portions extending from one side edge of the strap to the other, the upper and lower portions having laterally inturned side positions at at least one side edge of the strap, and a double layer of filler strip located between the upper and lower outer portions. The upper filler strip layer has a side edge portion located between the upper outer portion and an adjacent laterally inturned side portion thereof, and the lower filler strip layer has a side edge portion located between the lower outer portion and an adjacent laterally inturned side portion thereof. Each adjacent laterally inturned side portion is short compared to the width of the strip so as to leave substantial portions of the width of the filler strip layers adjacent each other.
