You might try some light weight denim looking cotton and flannel put some minky or wool between layers of batting for warmth and tie it. He wants the masculine look and he wants the warmth. Heavy is not necessarily warmer. He might be happier with 2 quilts rather than just one. If he has two he can take one off if he is too warm. The second quilt could just be some denim jeans pieced etc. and then backed with something or you could make it so the other quilt fits inside the pieced jeans for just a cover for the other quilt - that way it can come apart as needed.
