Reviewed: I Love DU/ER’s New Shirt Jacket So Much I Don’t Want To Take It Off

If you’ve heard the term “shacket” before, then you know they’ve been a cool weather staple in menswear for quite some time. But if you aren’t familiar, and the term wasn’t a dead giveaway, then I’m here to catch you up to speed and tell you about my new favorite shirt jacket that’s an inclusive piece of garb with the perfect fit and pairs well with several style situations. 

A shirt jacket, also referenced as a shacket or overshirt, is separate from your typical shirt. With facets of both a button-down shirt and jacket, it’s a versatile hybrid garment that gives you best of both worlds; offering extra style and warmth. It has the capability to stand alone, be worn over top of a tee or layered underneath a coat. That said, fall-winter time is mostly when the weather beckons for shirt jackets, however you can work them in between every season especially during those chilly spring-summer nights.

As huge fans of DU/ER, who SPY has repeatedly named the world’s most comfortable jeans, it’s no surprise their black weightless insulated shirt jacket lives up to the same hype — perhaps even more. It’s become one of my most prized go-to’s in my wardrobe. And you’re probably wondering, what makes it greater than the next shirt jacket on the market? Well, keep scrolling to hear my review.

At SPY, we love products including clothing items that are sustainable and reduce carbon footprint. That said, this shirt jacket is made from 100% recycled nylon and polyester providing all the comfort you wish for. A nice finishing touch are the all-natural corozo buttons along the opening made from the seeds of the tagua palm tree. Fascinating, right? I know.
