The nice thing about this tutorial is that you can really specialize these boxers and make them in a college print or something else that your guy would like. Check out the tutorial here.
Mama Tortilla's Neckwarmer
I love this pattern. First, it's sew simple. I mean you are literally sewing up a rectangle. You could even let your child sit on your lap and help stitch this one up as a gift for dad. Secondly, it is a great gift for any guy, especially one who love the outdoors - skiing, hunting, etc.here.
I know that these are women's mittens in the photo, but they really do make a great men's gift too. These things will cost you abotu $30.00 at a craft show, but they are cheap to make. They use up left over fleece scraps and a ruined men's sweater. So, if you have ever shrunk your honey's favorite wool sweater, you can make it up to him with this project by turning it into a great pair of winter mittens. Plus, these mittens are insanely warm. I got a pair last year for Christmas from my mom and they are a favorite gift still. If you don't have a wool sweater that is already shrunk you can pick one up for a few dollars at your local thrift store.

If you want a complete pattern, you can use the fleece mitten pattern from Simplicity or McCalls (both on sale over the next couple of weeks for under $2.00) and just substitute the felted wool sweater for the outside.
