What is down?
Down is the layer of fine feathers found underneath the exterior feathers of birds. Duck and goose down is most commonly used in down jackets because of the fantastic warmth it offers. Out of all natural fibres, down arguably has the greatest warmth-to-weight ratio and possesses excellent abilities to compress and recover, making it a great insulator. Down feathers are rounded in shape and made up of soft plumes, prongs and nodes that air. Whereas feathers are flat, rigid and aerodynamic for flying. As down also has a three dimensional shape it can ‘loft’ and trap more air than any synthetic material. By trapping air down, warmed by body heat it can keep the heat you generate inside your jacket, keeping you warm and toasty.
Are down jackets waterproof?
Probably not, but some down jackets and sleeping bags handle rain better than others. There are down jackets that have a waterproof, breathable outer material but they are few and far between, most down jackets are made with a windproof fabric that has been coated with a Durable Water Repellent (DWR) treatment. A DWR coating makes water bead up on the surface of the jacket and roll off, this means your jacket will shrug off a bit of snow and light rain but will become overwhelmed in really wet conditions. Water has long been the enemy of down. When down soaks up water it loses its loft, collapses, traps water and no longer offers any insulation. Recent advancements in chemistry, such as Nikwax’s development of ‘Hydrophobic Down’ which can resist up to 50 x less water than standard down is down that has been treated with a PFC-free solution that prevents down from absorbing water. If down doesn’t absorb water then it won’t lose its loft, if the down can loft then you stay nice and warm. Simple.
Should you clean your down kit?
Most definitely yes. Regular cleaning of your jacket or sleeping bag will ensure it a long life and make sure that it keeps performing at its best. Dirt on the outer fabric and body oils trapped on the inside of the jacket or sleeping bag stops the DWR working and will attract water, will stop the down lofting and these all need to be cleaned away. As a down jacket or sleeping bag is a specialist piece of kit made with delicate natural components and high-tech synthetic materials it’ll come as no surprise to you that there’s a very specific way of cleaning it. Don’t worry though as it’s really simple to do at home.
Nikwax Down Wash Direct is the best product to clean all your down kit and clothing as it’s specially formulated for hydrophobic and conventional down. It will effectively clean the item and restore its water-repellency at the same time safely and easily in your washing machine. Like all Nikwax products, its water based, PFC-free and doesn’t contain any harmful chemicals so it’s kind on the environment.
It’s best not to use conventional household detergent as the chemicals and perfume they tend to contain can damage down and they leave behind residues that will impair the DWR and loft of the down.
Anything else?
Remember the water repellent treatments on the jacket and the down? Well they wear off. Don’t panic though. Regular cleaning with Nikwax Down Wash Direct will revive the water repellency on both fabrics and down that is lost through normal wear and tear.
If you haven’t kept on top of cleaning your down jacket and a top-up from Down Wash Direct isn’t enough to restore the water repellency then all is not lost. Nikwax make a product called Down Proof that will apply a fresh DWR to down jackets and sleeping bags and will even make non-hydrophobic down water repellent. Just follow the instructions on the bottle and all will be well with your kit again.
