Carrying devices with a pair of shoulder straps are disclosed. Each strap of the pair of shoulder straps has a first textile layer sewingly stitched to a second textile layer that is shorter than the first with at least one magnet positioned and enclosed therebetween proximate or at a central transverse plane to form an intermediate. A third textile layer is sewingly stitched to the intermediate along each longitudinal edge to form the strap. The polarity of the magnet(s) in the first strap and the polarity of the magnet(s) in the second strap are oriented with the same polarity facing a top surface thereof, thereby the first strap is magnetically attractable to the second strap with a bottom surface of the first strap in direct contact with a top surface of the second strap or vice versa.
