Why Use This Product

Over time, waterproof garments can lose their ability to repel water as the DWR coating wears off. When this happens, the outer fabric starts absorbing moisture, which can reduce breathability by up to 70%, leaving you feeling clammy and damp inside.

Nikwax TX.Direct® Wash-In restores your gear’s DWR and breathability in one easy step, so your waterproof clothing continues to perform as intended.

Your gear could also be wetting out simply because it’s dirty. Before waterproofing, clean your garments with Nikwax Tech Wash®. If your gear is still new or recently treated, cleaning alone may revive its repellency. However, for older, well-worn gear, follow up with Nikwax TX.Direct® Wash-In to fully restore performance.

The Science Behind It

When we sweat during outdoor activity, moisture vapour must escape through the fabric to prevent overheating. If the outer layer absorbs water, this airflow stops — reducing comfort and increasing condensation inside your jacket.

Nikwax TX.Direct® prevents this by forming a flexible, breathable waterproof layer on every fibre, maintaining full moisture transfer while keeping rain out.
It treats seams, tapes, cords, and stitching throughout the garment, ensuring complete protection.

Unlike traditional treatments, no tumble drying is required — the DWR develops naturally as the garment air dries, saving energy and protecting older fabrics from heat damage.

Cleaning is as Important as Waterproofing

Ordinary detergents can leave behind water-attracting residues that block breathability and reduce repellency. Always use Nikwax Tech Wash® for cleaning waterproof clothing before reproofing with TX.Direct®.
Regular cleaning helps maintain long-term performance and extends garment life.

How to Use

1. Clean first: Use Nikwax Tech Wash® before applying TX.Direct®.

2. Apply by hand or washing machine according to garment care labels.

3. Air dry: Durable Water Repellency develops as it dries — no heat required.
