I just bought a windbreaker, made in China probably, nylon, lightweight, with a zippered-in hood and pockets for both hands.
The right hand pocket has a two pieces of elastic, about an inch wide, white, with plastic hooks/clips at each end that interlock, each 8 inches long. They're attached inside the pocket and long enough to come out of the pocket.
What are they for??
I borrowed a baby to see if it was a convenient way to carry one, you know better than on one's back or chest, making hanging from the side. But that did not work well. His toes kept dragging on the ground. I'm out of ideas.
