Why Use BaseWash®

Base layers work by moving sweat away from your skin to keep you dry and comfortable. Over time, dirt, sweat and detergent residues can reduce this performance, leading to slower drying and lingering odours.

Nikwax BaseWash® cleans thoroughly while conditioning fibres, restoring their ability to wick moisture efficiently and improving drying speed. This helps regulate body temperature and keeps you feeling fresher for longer.

Built for Performance

Unlike standard detergents, BaseWash® does not leave behind residues that block wicking. Instead, it enhances the natural performance of technical fabrics, improving comfort whether you're training, hiking or layering up in colder conditions.

Why Base Layers Need Proper CareSynthetic base layers are designed to sit next to the skin, regulating body temperature by moving moisture away from the body. These fabrics are highly breathable, fast drying and built for performance.However, over time, sweat, body oils and bacteria build up within the fibres. This leads to persistent odours and reduced performance.Standard detergents and fabric softeners can make this worse. They leave residues that reduce the fabric’s ability to wick moisture, slowing drying times and allowing odours to return quickly.Keep Activewear Performing at Its BestWhen your sports clothing starts to smell or lose performance, wash it with Nikwax BaseWash®. It removes odours rather than masking them and restores the fabric’s ability to manage moisture effectively.Use it regularly onGym wear
