I have 2 Down bags that I was thinking about treating to add some water repellence to them. Was considering using NikwaxDown Proof on them. As far as I know they have no treatment from the factory on them.

Would recomend or not recomend this?

Go for it. It not only restores but it adds water resistant characteristics. So even if they did not incorporate a DWR coating on the bag originally it really shouldn't cause ya any problems.

If ya just want to be 100% positive and get the answer directly from the folks at Nikwax here is a link for the contact info:

Thanx for the link.

Adding is what Im looking for, 1 bag an SD Ridge Runner 30 is brand new never been used yet the other a Marmot Sawtooth 15 is still like new, only been used 7 or 8 times so still clean and smelling purdy.

McNett ReviveX may be another solid option for ya. It revives/restores the DWR coating on materials. My thought is this.

In order for a DWR coating to need this process it is due to the DWR wearing off over time. Now to me this is almost the same as the DWR not being there in the 1st place. 

Here is a link for the product:


Personally I would contact the companies just to be certain. Noone knows better than the manufacturer.

Thats why I wanted to ask for opinions first. I would hate to trash or comprimse my new bags. I'll have to contact them and see what they got to say.

I can't see there being any problem with the use of either product but its always better to be safe than sorry. The more info you can get the better. I am pretty certain you are ok on this one though.

@ azrhino :  A few months back I washed my old Holubar with Nikwax Down Wash and then used Nikwax Down Proof.  First off the bag had been in it's stuff bag for many, many years probobly around 15+/- years (not recomended).  When I found it and pulled it out of the bag it was flat and I mean really flat 0% loft.  As I had gotten it at a garage sale years ago and just used it a couple of times I just stuffed it I guess I did not pay atention to how truly dirty it was.  So it was flat and stinky and not even close to the colour it was suppose to be.  I considered throwing it away.  Then after some thought I decided to Use the Nikiwax products and low and behold the the bag Looks like a new bag woth full loft.  I cannot tell if the Down Proofreally worked or not, its hard to tell unless you previouly had a problem and then the problem does not occure after the treatment.   As it only costs $14 if I remember right, I jus figured ti would be worth the expence since I was already washing it.  After reading the product info if it does do what it says it will be well worth it as this bag is old and does not have any of the newmaterials that help it say dry.  I read many reviews and I could not find a single bad thing said about Nikiwax.  I'm wondering if your Marmaot Saw tooth is the EQ model?  Just wondering.  I would say if these were my bags i would just wash the dirty bag and use the newer Marmot until it's dirty and needs a good washing and then add the Down Proof if so desired.  I have used Marmot down bags for years and I have never had any problem with mositure retention in any of my Marmot down bags.

No Sawtooth is not the EQ. Neither bag is dirty or needing a wash, was just thinking of adding some repellency I guess just for the heck of it. Like ya said, $14 and a wash is a cheap way to improve something if it works.

I sure cant complain about the Marmot bag. I roast in the thing when temps are mid 20's and have a lite base layer on. Thats why I got the SD with a little higher temp rating. Have'nt tried it out yet.

here's the reply I got from mcnett,

Hello Robert,

Thank you for contacting us. I would begin by cleaning the
sleeping bags with ReviveX Down Cleaner (http://www.mcnett.com/ReviveX-Down-Cleaner-P175.aspx). Dirt
and oil can severely inhibit water repellency, so you should always begin by
washing the bags.

Once you have washed them with the ReviveX Down Cleaner, I
would recommend spraying the bags with our ReviveX Spray-On Water Repellent (http://www.mcnett.com/ReviveX-Spray-On-Water-Repellent-P316.aspx).
The ReviveX Spray-On Water Repellent does require that you place the sleeping
bag in the dryer. I would recommend reading your sleeping bag care instructions
(I was unable to find garment care guidelines for either model of sleeping bags)
first to make sure the sleeping bags can be placed in the dryer. If they cannot,
the next best alternative is our ReviveX Air Dry Waterproofing Spray (http://www.mcnett.com/ReviveX-Air-Dry-Waterproofing-Spray-P177.aspx).

Let me know if you have any additional questions.

Have a great day!
