Published Jan 18, 2026

Down can be rendered ineffective if it gets wet, as its loft collapses, reducing its insulating power. Therefore waterproof down jackets or water resistant ones are extremely useful. Some will come with a durable water repellent coating (DWR) to repel water, but you can also add this yourself.

Is it normal for feathers to come out of down jackets?

Print. Noticed some feathers poking out of your new down jacket? No need to worry - this is totally normal for any down product! When you wear a jacket for the first few months, the feathers tend to move around as they settle and the sharp quills on the feathers can poke through the seams.

Can you put a down coat in the washer?

Do NOT use bleach or fabric softener when washing your down jacket. You'll want to wash your down jacket on the permanent press or gentle cycle on your washing machine and use cold water. It's best to steer clear from warm water or hot water when washing your jacket.

Are down jackets Durable?

Because they're meant to be worn as an outer layer (you'd be hard-pressed to squeeze a hardshell overtop such a lofty piece), heavyweight down jackets also feature a durable, water-resistant shell and handy extras like internal stash pockets, which are great for storing skins or keeping your climbing shoes warm.

Is down warmer than polyester?

Down is lighter and weight-for-weight it's warmer than synthetic insulation.

Do down jackets lose warmth over time?

Like we mentioned above, no insulating material beats down in terms of warmth per ounce. Additionally, down is very resilient, and unlike other fabrics or insulators, it will not thin or wear if cared for properly. Fleece and synthetic insulation will lose loft over time, thereby decreasing their insulating qualities.

How can I improve my waterproof jacket?

A waterproof spray will help reproof your jacket to maximise its waterproofing and breathability. Always wash your coat first if re-proofing using a waterproof spray. Dirt and oil can clog up the breathable membrane found in many waterproof jackets, making it feel as though water is penetrating through the fabric.

How do you waterproof a rain jacket again?

After washing the jacket, rinse it and, while it's still wet, hang it. Now comes the time for re-waterproofing: Spray the jacket—and spray it really well—with a waterproofing spray. I like ReviveX Spray-On Water Repellent. Then put the jacket in the dryer, and when it comes out, it should be hydrophobic again.

Can I machine wash a North Face down jacket?

This can cause loss of loft, the ability of your down product to keep you warm. Use a front-loading machine ONLY. A top-loading machine with an agitator may damage the product's internal construction. Wash in warm water with a mild powder detergent (without bleach) on a gentle cycle.

Is 15K waterproof good?

A rating of up to 10K is enough to handle light to average rain for a short amount of time. Ratings between 10K and 15K can handle a moderate amount of rain for much longer, and jackets rated between 15K and 20K or higher are serious shells for heavy, intense rain over a prolonged period.

Are all waterproof jackets windproof?

Windproof: Any waterproof jacket is also windproof. That makes sense when you consider that a barrier designed to block driving rain would also block the wind that's pushing the rain. You will also find jackets with windproof technology, typically some type of laminate, that are only considered water-resistant.
