Nikwax TX DIRECT 1 Litre Wash-In Waterproofer for Outdoor Gear. Safely, Revitalises Breathability & Water Repellency of Waterproof Fabrics. Recommended for Gore-Tex, SympaTex

Used it to renovate the DWR on a couple of items and it worked well, water now beading off the items

I had a coat that was waterproof, with a hood, and had washed it in the washing machine. Unfortunately, it lost its proofing, so when it rained heavily earlier this year I got soaked. The clincher was a walk round the lake at Clumber Park. I decided to try this and the corresponding proofing treatment.The Tech Wash is a gentle detergent that is not going to remove any proofing treatments. After a machine wash with this at a low temperature, I used the Nikwax proofing, which also goes in the washing machine, like a detergent. After checking labels, I did a low temperature tumble dry and then tested in the next storm. (Luckily, in the winter or 2013-14, storms were reliable and I didn't have to wait long.The result was that the coat was waterproof again, and I remained dry. As I could not easily find a replacement for the coat in question, even at a large Go Outdoors, I am really pleased about the results. Yes, I know I will have to re-proof the coat in the future, but for just a few pounds per proofing I thought this was a bargain.

I have used Nikwax products for a number of years now and I always go back to them. They work perfectly as long as you follow the instructions to the letter. I have used the TX Direct on waterproof jackets and trousers of multiple makes and it always works really well. Its important to thoroughly wash out your washing machine detergent tray before you use it and always wash garments in a detergent free mix first to get rid of any grease or dirt. I always use Tech Wash for this which does the trick. Great product for restoring the waterproof film on clothing and getting the rain beading again.

Good product - easy to use and does what it says it does on the label

It’s a must have for walkers and anyone who is out in the elements a lot.

Easy to use and coats are very waterproof after use. You do need to use quite a lot per garment. It's not cheap but coats last longer.

Didn't realise you could re-weather proof items so easily.

Purchased to replace same product in use. Tip - if you have a dirty item that will not shed water effectively after washing with this product and re proofing then give it a couple of washes with normal clothes detergent. I recommend a couple of rinse and spins then use this product and then use a re proofing product e.g. TX Direct Wash In or similar.
