Ah, the age-old question! The short answer is, yes. The more in depth answer is, it depends.
Goose down is known for being highly heat retentive while being simultaneously light and compressible. The downside is that frequent washing can result in a loss of loftiness and feathers over time. What’s more, down also doesn’t like to stay warm in wet conditions.
Luckily, parkas and other jackets featuring a hydrophobic outer shell keep water out. That way your feathery interior always stays toasty!
Do consider that puffers (or, as some of us like to say, puffies) are typically considered water-resistant as opposed to waterproof. They’re best paired with a removable outer shell on rainy days. And, as always, be sure to carefully follow washing instructions as indicated by the hangtag found on your garment.

Canada Goose fills their parkas, jackets, and vests with a mixture of down. All of their down is certified with the Responsible Down Standard (RDS) stamp.
In addition to ensuring that their down-fill is always a by-product of the poultry industry, this stamp certifies that the Five Freedoms of animal welfare are tightly followed. This means that live-plucking and force-feeding are forever prohibited.
