On mine, the bcd and pockets are nylon. I used a lighter to melt the nylon and to stop all the fraying. The melted plastic lip this creates keeps the thread from pulling through. I bought a medium nylon thread from JoAnn's fabrics for the sewing and just did it by hand with kind of a lock stitch. It worked out fine. Its probably weaker than OEM, but you're not going to be putting weights in the pocket again, are you?
Reserved for my tiny backup flashlight from now on! I just can't stand looking at the frayed edge sticking off an otherwise good looking BC!
