I use borax to keep the funk down, as well as vinegar. I wash in cold water (warm occasionally on some fabrics), and dry either on low or air dry (fabric dependent). When I wore white gi, I would bleach a few times a year.Part of the wear and tear on a gi is how you wash it. I'd recommend never bleaching the gi. It will weaken the fabric over time, and can also make it stiff.
I'm a big fan of adding vinegar to the wash. Helps with funk, with stains and is kind awesome.
Those ripstop pants are nice and light, but I can't seem to get a pair to last more than a year.
