It works wonders with cotton/ cotton blend clothes already treated with DWR from THE START from the factories.This product is for reapplying already DWR-ed clothes/ gearsDo not expect this cotton proof to make regular heavy cotton things into mil-spec'd rain gears.It kinda worked on my Pendelton canvas jacket.Just like me, experiment this product on your old cotton/ cotton-blend clothes.

This stuff is pretty amazing but it should be changed to COTTON RESISTANT I used this on my denim jeans and it just makes it harder to absorb water. Awesome for proofing your jeans to ride motorcycle and not carry so much rain with you. Recommend to anyone who is in a rainy state.

This product works well for light sprinkles of water. I used this for my motorcycle jeans as its original water proofing has worn away. Right after washing I noticed the cloth felt quite different. I tested it with some water spray and it did a good job. However, if it was patted with water or a wet towel the water will soak into the jeans. This will work for puddles and splashes. However, when I get on my bike and there is some water dew on the seat, the water still soaks into the pants... eventually.

I have a Carhartt duck cotton jacket. I live in the pnw. These two things don't mix well because it rains so often here. I actually used the entire bottle on just my jacket figured we would do extra strong so it really was waterproof.The phrase "disappointed" doesn't begin to describe my opinion of this garbage. It might have well just been water. It absolutely did nothing. It's not even slightly waterproof. The before and after are exactly the same. I could upload pictures but why even do that when literally nothing changed. Honestly I would never recommend anything from this company because of the zero star results I received.

I was a little nervous given the variability on some of the reviews but I washed my M65 field jacket with tech wash and then cotton proof in my washing machine and I have to say that I'm pretty impressed, water beads up on rolls off similar to what the other field jacket user reported. Short of waxing, cotton will never be truly waterproof but I would say that if there were light rain or showers in the forecast I wouldn't be concerned.In the bottle the proofer smells a little like Elmer's glue with a trace of vinegar but I can't detect it at all on the dried garment.

Verhoogt windweerstand en verhindert waterabsorptie. Getest opPolykatoen. Maakt kleding in ieder geval sneller drogend en grotendeels waterafstotend maar niet waterdicht.

Tja... Lite nytta gör en behandling men bara marginell effekt... Inte värt pengarna i mitt tycke.

This is a great product. My husband is a surveyor and he was in the rain and tall wet grass all day and stayed dry. He also said it cut the wind really well and it was 30 adn 40 MPH wind that day. If you do not do these extra steps the product won't work well. If you do these extra steps it works great!First we ran our washer with vinegar ( put 2 to 3 cups of vinegar in where liquid detergent goes and hot water to remove detergent and fabric softener build up through out my machine. It is in your machine even when you cannot see it. I hadn't used vinegar in awhile so we done this procedure twice. We washed my husbands clean pants from the closet with vinegar only (2 cups) on a long wash and no fabric softener. Actually we ran them a second time on a short wash with vinegar and then a rinse/spin only. Then we soaked his pants in a 5 gallon bucket of water with the product for a several hours. We dripped them out well and put them on a mini short rinse and spin. We dried them with HOT HEAT.It works!
