I've spent the last couple years of trial and error with rain gear here in western WA. Here are my observations:
- Highly flexible and quiet gear leaks
- Soft, quiet gear soaks up water and becomes heavy
- Polyurethane coated keeps the rain out but the sweat in
- Thin, ultra-packable tears easily
- Less than 3 layer construction wears the membrane and will leak
- Loud rain gear is likely not loud about 10 yards away, even less if it is raining
- Anything less than 10,000 MM/24 gets water pushed through from brush
- DWR is like a driveway gate preventing a burglar from getting to the locked front door
- Breathability matters more on top than on the bottom
Here's what works for me:
After trying over half a dozen styles and brands, FL SEAK jacket performs. Schoeller pants with DWR and a base layer can handle a lot via body heat evaporation but the Nomad Hailstorm pants will be worn all day over a base layer instead for late season.
