Why Down Loses Its Warmth When DirtyDown is prized for being light, compressible, and incredibly warm. Its insulating power comes from the way the fine filaments trap air, which your body heat then warms.But through use, dirt and body oils build up on both the fabric and the down fill. Dirt attracts water, and if the fabric absorbs moisture, rain and condensation can seep into the down. When down gets wet, the filaments clump together and lose their loft. Without loft, down can’t trap air, meaning it loses all of its insulating properties.Wet down also gains weight, breathes poorly, and conducts heat away from your body up to 25 times faster than air — leaving you cold, damp, and at risk of hypothermia in severe conditions.Why Down Performs Best in Dry ConditionsDown offers the best warmth-to-weight ratio of any insulation, which is why it’s used in sleeping bags, jackets, vests, and expedition gear. But its weakness is watereven condensation from sweat can collapse insulation.That’s why it’s essential to maintain Durable Water Repellency (DWR) on both the outer fabric and the down fill. Nikwax Down Wash Direct® safely cleans away contaminants, revitalises insulation, and restores water repellency.When to Use Nikwax Down Wash Direct®If your down gear is dirty or soaking up water, first wash with Nikwax Down Wash Direct®. This removes dirt, sweat, and detergent residues that mask DWR.
For newer or recently treated items, washing may be enough to restore water repellency.
For heavily used gear, follow up with Nikwax Down Proof™ after washing to reapply DWR to both fabric and down fill.
Why Standard Detergents Don’t WorkConventional detergents leave behind residues that attract water, causing down and fabrics to wet out. They can also reduce loft by redepositing dirt inside. This is why specialist care is essential. Nikwax Down Wash Direct® is formulated specifically for down gear, cleaning safely without residue, and restoring insulation and DWR.How to Care for Your DownWashingUse a gentle cycle with a slow spin. Wet down is heavy, so spin several times, increasing speed gradually to protect baffles.
RinsingMake sure items are thoroughly rinsed.
DryingTumble drying is strongly recommended (if the care label allows) to restore loft. Tease apart clumps throughout the process. Leaving down damp can permanently damage it.
Air dryingAfter tumble drying, air the item in a warm, dry space for at least a day before storing.
