Usually 60/40 cloth has the warp of the fabric of one material (cotton) and
the weft of the fabric of the other material (poly). This may cause for some
unusual shrinkage. I remember from working at a hiking shop that this was the
case. There were jackets made of a 65/35 cloth that was a twisted combo yarn.
Best advice is to test thoroughly.
