Gear AID Revivex Durable Water Repellent (DWR) Spray for Waterproofing, Restoring Performance on Nylon Jackets, Gore-TEX, Paddle, Snow and Camping Gear

This product is spot on and it is so easy to apply brings the gortex back to life thank you.

After washing my waders with Gearlab Revivex Pro Cleaner and then coating them with this DWR spray the waders had that like new water shedding ability.Only been out once after treatment and will have to see how long it lasts.So far so good.

Worked great on my ski gloves, Mountain Hardware jacket and trousers. Wasn't much left after that. Just bought another bottle for this year as it really did the job.

Used on tent and rain gear. Works exactly as it should greatly improved water sheds g ability of even a very old tent rain fly. Works as you’d expect it to. Very good stuff.

I purchased a bottle of this stuff several months ago, but have deliberately held off reviewing it because I wanted to be sure. I waterproofed the jacket of my Rev'it textile motorbike gear a few weeks back and have been waiting for a good downpour in which to test it; I've just returned from an 8-mile ride in torrential rain, quite dry from the waist up, so I feel ready to recommend it. I deliberately only waterproofed the jacket, as I wanted a basis for comparison. The pockets of my trousers, the areas around the zips and velcro, are all sodden; even in this short journey, water had soaked into all available entry-points and down my legs into my boots. Had I had any paper or electronics in the trouser pockets, they'd have been ruined, and my feet were cold. By contrast, the recently-waterproofed jacket is absolutely unaffected. I dried my hands and ran them over the inner lining, through the pockets and even down the inside of the front fastenings, and all were COMPLETELY dry. True, I wasn't out there for hours, but water is water, and this is as good a litmus test as you need. No water soaked through any part of the jacket at all, and I'm confident it would have held up for much longer (this isn't my first rodeo in monsoon motorbiking; I know what to look for.) It definitely works, then. But before you buy it, a couple of caveats... First, it is an absolute PAIN to apply. Where other waterproofing products for camping, hiking and so on can air-dry (and cost about half as much per volume), this stuff needs to be 'heat-sealed', meaning tumble-driers or similar. I don't have a tumble-drier, so I hung the jacket in the hallway, surrounded it with electric heaters and turned a hairdryer to it for the best part of an hour. This clearly did the trick, but it was an absolute chore. Even spraying it on, with this small, stiff pump-action bottle, took about 20 minutes and tested my patience. Second, it's worth mentioning the quantity. This bottle isn't very big and you need more of the stuff than you think - I'll be buying another to make sure I have enough for my trousers and gloves. One bottle barely sufficed for my jacket, which was disappointing. There is enough to superficially spray a large area, for sure, but to make sure you've waterproofed a fabric effectively you need to ensure that the entire surface is well-doused, not just lightly misted, and that takes a lot more than a once-over with this spray. You'll find yourself using it up very quickly, going over areas repeatedly to get every nook and cranny, so factor in the cost of a couple of bottles if you've got a full set of clothing to do - three or four if you're planning to do a tent or similar. For me, it's the results that matter, so I don't regret the time or effort involved in using this stuff. It really does work. I understand from many sources that waterproofing is NEVER permanent, and that I'll probably be reapplying it in a year's time at most, but for the effectiveness of the waterproofing, I'm happy to. People wanting a less time-consuming and merely adequate result for winter coats and cycling trousers, however, might want to look at the wax-based budget sprays available in local outdoors shops - they do a good enough job for regular purposes, and take much less time to apply. This is a specialist product with a suitably involved treatment process, and not everyone will need it.
