Nikwax Down Wash Direct (300ml)
Gentle, effective cleaner for both regular and hydrophobic down that won't weigh down or clog the plumes, so your garment or sleeping bag retains its insulating loft. Sleeping bags should be washed by hand (bathtubs work well) or in a professional washer. To wash down clothing in your own machine, add 100ml to the clean detergent dispenser (max 2 items in the machine) and set the cycle on low with slow spin. After the washing cycle has completed, run multiple spin cycles incrementally increasing speeds to remove excess water. Tumble dry your item until clumps have disappeared.
