I like that there are photos of these to help you choose. The gray scarf for men looks good to me, but your guy might prefer a brown or camel tone. Or you could ask him to pick out the yarn. Guys can be picky about what colors they will wear. Sometimes they will wear the colors of their favorite team. Click the label “team colors” below this post for more ideas along these lines.
The cowel scarf is beautiful, and I’m intrigued by the black & white diagaonal pattern with some fringes included in the pattern.
