Nikwax non-detergent soaps, Tech Wash & Down Wash Direct, clean without harming water-repellency and help to restore the bag's loft. Nikwax waterproofing treatments are made from a breathable elastic water-repellent elastomer called TX.10 that bonds to the fibres of the fabric and fill material. Treating sleeping bags with Nikwax makes them less susceptible to humidity and allows them to stay drier longer.
“We will often double the lifespan of our tents using the wash and proofer. The Sam Sykes and MAMMUT Mountain School UK clothing and equipment is always washed and proofed with Nikwax products. Without the capability of Nikwax products, we could not operate at our best - especially when it really counts! All professional operators in the Outdoor Industry will wash and proof their clothing and equipment regularly. The benefits range from product longevity, protection, sustainability and aesthetics. In short, if you’re not doing this, it’s time you started. Nikwax gets 10/10 from me!”Sam Sykes
