ABSOLUTELY amazing!!
All I wanted was my "old" goretex shell back!! It's probably 15 years old -- but the one of last times I used it, packing out a total hunting camp in the rain, I was soaked to the skin. I told an old friend of mine(who had once upon a time owned a sporting goods store) about it, and he suggested getting Nikwax. I was a little "wary" about what it would do to the washer....but NO WORRIES! I wanted to get the best bang for the buck -- 5 oz. would do two items, so I threw in a fleece pullover w/ the shell. After the washing machine treatment (SO EASY) I actually dumped water from the faucet on both items-- and gleefully saw the round water balls shedding off both. I'm going to purchase A LOT of this, for all the items that are recommended for use -- can't go wrong (AND, I can return all the little "girly" goretex snowbunny jackets my husband got me for Christmas when I said I wanted Goretex) ---- Nikwax Polarproof gave me back the real parka I wanted.

Great Product, Great Company
I use this stuff once in a while to refresh the waterproofing on my Covercraft, "sunbrella" car cover. I also throw in a pair of pants (poly/cotton blend) to become part of my "stealth" rain gear.

like magic
this really adds water repellency to polar fabrics, enabling them to make the difference between comfort and misery in a surprise drizzle or in high humidity situation.

Works Great!!
Really easy to use and seems to do the trick, brought the beading up and rolling off of the water-proofness back to my 5 yr old columbia jacket with no prob.

Refreshed the fabric wonderfully
Used this to revitalize my North Face Denali Jacket. It appears to have brought life back to the fleece in the jacket after a winter of hard wear. I'll have to wait to see about the renewal of the water repellancy, but I have trust in the product to do what it says it does. I'll keep bying it no matter where I live or what clothing I have to use it on.
