The designer Terence Simmons invented the Swack, which is short for sweater and backpack combined, after escaping a serious injury due to a fall that resulted from a backpack strap that got entangled in his crutches. So now you don’t have to worry about your straps getting tangled anymore? Why not hide the backpack too so that it won’t get tangled? I never thought that straps were that big a hazard. Just saying.
