I’m just wondering if there really is a lightweight (no insulation) rain jacket that will STAY waterproof.
One other brand I saw that was at least moderately affordable was Outdoor Research. Marmot was another.
Here’s an example of what I’m looking at… just would love some feedback on non-Gore-Tex stuff that is and STAYS waterproof.[/QUOTE]
Your expectations are a bit unrealistic if you think there is any jacket out there that is truly, and will always stay, waterproof. Waterproofness is just a sliding scale as no widely accepted waterproof industry standard for fabric exists. It’s all based on the pounds per square inch of water the fabric will let through depending on the amount of force applied (wind driven rain, for example.) So a light rain jacket with nothing more than a DWR finish can advertise as being waterproof just as a three layer laminate jacket with taped seams can advertise as being waterproof. The difference is the degree of waterproofness. The jacket with just the DWR finish is built to withstand light rains, while the 3 layer laminate was tested for more forceful rains.
“Gore-Tex” has become the Kleenex or Band-Aid of the waterproof fabric world. Once its patent was up, competitors jumped on board to create Gore-tex equivalent materials. Many perform just as good or better than Gore-Tex, so don’t be sold just on the name.
OR and Marmont are great brands. I’ve had both, in addition to about every main line brand (TNF, REI, Columbia, Arc’Teryx, etc… I’m a jacket junkie). Just make sure any jacket you get has a rating of 2psi or higher (if you can find that information), taped seams, a laminate (so multiplayer, not just a topical DWR finish) and that the jacket is listed as breatheable. What you don’t want is to keep out the rain, yet let your body’s natural moisture stay trapped inside. Pit zips are also extremely helpful in letting out trapped heat and moisture if you plan to do much physical activity in the jacket. That’s a mandatory feature for me.
Here is an excellent write-up about waterproof rainwear I think you will find very informative:

Also: NEVER wash a rain jacket (with a laminate or DWR finish) in the laundry with regular detergent.
Hope this information helps!
