Cotton proof works by coating the individual fibres with a flexible water repellant treatment so they can't soak up as much water whilst allowing moisture vapour to pass through.  This process reduces weight gain from water ingress and maintains the natural breathability of cotton.  Easily applied in a washing machine, which ensures the treatment gets right thorough the fabric.  However if garment care instructions restrict machine use, hand proofing is effective. The Durable Water Repellency (DWR) develops on air drying, there is no need for tumble drying.  For used and dirty clothing we we recommend that the garment is first cleaned with Nikwax Tech Wash on a separate cycle, there is no need to dry before re-proofing, just bung in the Cotton Proof and start another wash cycle.

Nikwax waterproofing products are completely environmentally friendly.  They are water based, non aerosol, non -flammable, non hazardous, contain no harmful solvents or volatile organic compounds and are completely free of flurocarbons.  Which is nice.

Excellent customer service. Really detailed easy to understand product descriptions on the Trekitt website, and gear reviews on the Trekitt YouTube channel made it so easy to choose the right backpack for me.

Emily - May 2020

Amazing service! Very helpful in regards sizing and what most matched my needs, despite this being done over the internet. YouTube videos of products being examined are very useful also. Would definitely use again, very fast and efficient delivery. Brilliant! Highly recommended!

Highly recommend. I usually go to the shop in Hereford as staff are alwasy very helpful and knowledgeable. So this was the first time I have purchased online and the service was just as good as the shop.
