What caused a year-old Black Diamond climbing harness to fall apart? According to the owner, it had only been used about 70 times indoors and had been stored carefully. So when the threads holding the buckle fell apart, it was quite a mystery.
The harness had abnormally pinkish threads. The QC crew at Black Diamond set out to find which chemicals change the color of nylon threads.
