Jarred_Jackman Posted February 9, 2004 Share Posted February 9, 2004 For a bag that doesn't have some sort of eater repellent or water proof shell on it, would DWR work very well. What are some suggestions for coating a bag with a substance that will do it's best to keep out dew, light spin drift, that type of stuff, Im' not looking to have it stand up to a deluge. thanks Jarred Quote Link to comment Share on other sites More sharing options...
Rodchester Posted February 9, 2004 Share Posted February 9, 2004 DWRs can help MOST any material shed water. It works very well (OK, decent) with nylon, which is likley what is on your bag. Most bags come with some DWR on them. Quote Link to comment Share on other sites More sharing options...
max Posted February 9, 2004 Share Posted February 9, 2004 I was told by a "knowledgable sales person" that these new lightweight bags should be kept away from waterproof breathable treatments because the W/B agent will eventually get to the down and be (very efficiently) wicked away into the down, where it decreases the loft of your sleeping bag. Seem reasonable to me, but I sure can't say I've ever seen this or have any proof what so ever. I just realized your post isn't really specific to lightweight bags, but I guess the above would apply to warm bags too. Quote Link to comment Share on other sites More sharing options...
marylou Posted February 10, 2004 Share Posted February 10, 2004 Uhhh. Max, that person must have been on the crack pipe. Jarred, I wouldn't count on being able to DWR a bag with a bottle or two of Revivex and getting too hot a result. Just go buy a new bag if you want one that's treated.

catbirdseat Posted February 10, 2004 Share Posted February 10, 2004 I've used this NikWax stuff. I can't claim it works all that great. Quote Link to comment Share on other sites More sharing options...
JoshK Posted February 11, 2004 Share Posted February 11, 2004 I am getting my next bag made with some highly waterproof DWR fabric on the *inside*. that way at cold belays I can simply piss myself and drain the bag out in the morning.

Pro Mountain Sports Posted February 11, 2004 Share Posted February 11, 2004 Revivex sold here will renew your DWR and make your bag almost water proof for a couple of days. A little Revivex and heat from a dryer. Easy to apply. Maybe there is someone who has tried this who can report their results? Debate the weight.

Fromage Posted February 12, 2004 Share Posted February 12, 2004 Jim, I must say that mixing Revivex with a little gin makes it go down pretty easy. Plus after a couple G+Rs you don't need to put yourself in the dryer. Quote Link to comment Share on other sites More sharing options...
