When I first got them, I thought they would be great, with the elastic give. First time I wore them was to a structure fire. The leather eyelets stretched on 2 out of 8, causing the suspenders to detach from the bunker pants. The useful service life of these suspenders was less than 8 hours. Also, the friction between my t-shirt and the suspenders made the ends of the suspenders at the H start to fray.
