Do you have a photo? When you say bleached, is it legit bleached? Like spots have lost color altogether?
I have an older EG cotton ripstop jacket that gets some whitish patches, but I don't know that I'd describe them as bleached. If you get the fabric wet it returns to its old color.
In any case, I'd expect that it's specific to the fabric or to cotton ripstop. I'd try to return if you think it's defective.
