I’m been tossing around the idea of converting a lightweight windshirt to a full rain jacket. I’m wondering if you’ve had any experience or insight into a project like this.
I’m wondering if it would work to take a lightweight wind jacket, something like the Montane Featherlite Smock (3.5 oz.):
and using a wash-in waterproofing coating like this:
The idea would be to take something that’s water-resistant and make it waterproof. If this works, one could end up with a very lightweight rain jacket. I should mention that I also wear a broad-rimmed hat with a long “cancer screen” that would protect my head and neck.

IMO, the term “waterproofing” is very often made confusing by marketers. To me, a jacket that can keep you dry for a while is water repellant or water resistant. The only waterproof jackets are those that can keep water out even under hours of downpour.
Spray-on’s / wash-in’s can increase a jacket’s water resistance. However, unless your jacket is waterproof to begin with (e.g. PU coating), after-market products won’t make it waterproof. Too bad, cause otherwise, we can all be enjoying 3 oz. wp/b jackets! Obviously, this is not the case.
Here’s an idea I have been toying with (but haven’t actually tried): turn a wind jacket into a very highly water resistant jacket by using a combination of:
(1) Spray on water repellant treatment (or so-called waterproofing treatment in “marketer language”).
(2) Coat the undersides of the jacket’s shoulders and hood — places where rain would hit the most — with seam sealant or equivalent, to make those areas truly waterproof.
The end product is a very lightweight “hybrid” jacket that is (1) waterproof / non-breathable in strategic areas where rain hits the most, and (2) water resistant but very breathable in all other areas.
Thoughts, anyone?Oct 16, 2006 at 10:56 am #1364927

1. cut down (or not) a driducks/drop stoppers jacket in waist or arm length
2. wear it UNDER montane featherlite
for an ultralight “inner” rain jacket. Cut down it should weigh maybe 4 oz. or less.
