The Best Synthetic Down Jackets to Keep You Warm in 2021

Down has always been the gold standard for winter warmth because of its unparalleled insulation abilities. Down comes from the soft feathers of birds found under their outer feathers. Down is used in jackets are used in much the same way — it fills the inside of quilted or puffer jackets, providing an inner layer that protects against heat loss. However, down isn’t the only option. Synthetic down fills have gotten lighter and warmer, bringing them closer to their natural competition.

Synthetic down jackets have a few benefits. They’re typically cheaper, allowing you to get your winter warmth without having to sell all of your other clothes. Plus, while down is comfortable physically, it might make some people might feel uncomfortable ethically. Down is plucked from birds in a variety of ways, but not always in a cruelty-free manner.

Synthetic fills are not made from animal products, but that doesn’t mean they earn a perfect score on the sustainability front — they’re made using polyester, a petroleum-based product. Fortunately, tons of jackets use recycled polyester and nylon to at least reduce the environmental impact. Jackets on our list from Patagonia, The North Face and Everlane all use recycled polyester for their filling. There are also many different styles available for synthetic down, so you can find a jacket that suits your sense of style.

Whatever reason you’re looking for a synthetic down jacket, we’ve rounded up some of the best options, including from outdoors stalwarts Patagonia and North Face, as well as more fashion-focused brands.

9. Carhartt Duck Arctic Vest


There’s a certain age every man reaches when he feels compelled to purchase a vest. For some (see: finance bros), that age is in your 20s and 30s, and for others, it’s once you become a father. A vest just makes sense; you can keep your arms free while keeping your core warm, or you can layer up with a warmer outer layer when it’s really cold. This gilet has a warm polyester fill (“duck” in the name of this jacket refers to a type of durable cotton canvas, not a type of down filling). This vest comes in black or brown.
