Look to be pretty decent. As long as they are sewn properly. Not too sure about the bleaching, but that shouldn't be too difficult. I'm not thrilled about the current exchange rate either.
I agree with TM, it looks fat. If you don't cut that upper lip off, it'll be hard to conform to the shape of the helmet (if it's like sealsdirect). Heck, I cut the lip off of the sealsdirect stuff and still had trouble with it.
