Every so often, your Brooklyn menswear writer stumbles across one of the best menswear deals, a deal that’s too good to be true (nearly) and yet, simply has to be shared here on the blog (and far and wide, of course).

And one of the country’s best menswear designers is to thank for the deal in question today, which gives you instant access to one of the best shirt jackets for men … all at nearly 60 percent. Yessir, that’s right — it’s all part of the always well-stocked Todd Snyder Sale section, of course.

And within that Todd Snyder Sale section, this particular shirt stands out quite nicely: It’s the Todd Snyder Alaskan Chamois Shirt, a piece that channels Snyder’s trademark rugged-meets-refined sort of energy. It’s both one of the best shirt jackets for men and yet a piece that you can dress up slightly (say, atop a turtleneck for a touch of devil-may-care style).

And again, this discount brings this carefully crafted chamois flannel shirt down to $84, all the way from $198. With a full fit meant for layering, who’s to say how many different ways you can wear your new favorite shirt jacket this fall. As for me: I’d wear this rich and rugged shirt jacket, or “shacket,” atop my favorite henley or a thermal crewneck sweatshirt for exceptional fall warmth and timeless style.

Best of all is the fact that it hails from one of the country’s best menswear designers, and is built to last — all in a rich, fall-friendly pattern. It’s a deal worth shopping ASAP on this fine Tuesday, my friends. Go forth, layer up and let’s get after it this fall.
