Freddy, thats good to know. My K1 carbon rib vest totally came unstitched where the buckle straps attach to the carbon. This happened on 2 of mine on BOTH straps as well as my brothers. I fixed mine with some screws and time, my brother moved to a different brand.
I have a couple Sparco suits on order, so that is nice to know they are of better quality. I will have to try your wash trick next time. Sometimes dollar store has some hidden gems in their cleaning supplies.
