I have owned many pairs of suspenders, but none of them as good as these. All the others always have an end come loose, but these Contractor Series suspenders never turn loose! I have been wearing them for 8-9 hours a day working construction and they always hold tight. The secret is small pins in the catches that go into the cloth to keep them attached. And the cool thing is when you take them off, you cannot see a hole. Therefore they hold tight but don't damage your pats.
