Fabric is too "stiff" and doesn't breathe like classic cotton oxford. Sent it back. Glad I bought a lot of untreated cotton oxfords before they started offering only wrinkle-resistant. I think the untreated cotton will come back. I recall the same problem when the 60/40 fabrics came in.
When my husband comes home from work, his shirt looks as crisp as it did when he left in the morning. And what a great bargain these shirts are! Not only reasonably-priced in themselves, but we have kissed our shirt service good-bye and are enjoying the weekly savings.
