The best way to look at waterproof breathable rain gear is it’s 99% waterproof. There are just some conditions having to do with the humidity, the dewpoint, the amount of body heat you are or are not producing that will affect the performance. I have hundreds of days spent in the rain in rain gear of different brands with clients with different brands of rain gear so I get to see the performance of all brands. just because the fabric has “wetted out” doesn’t mean the rain gear has failed. Just because the first layer underneath your rain gear has a bit of water on it doesnt mean your rain gear has failed. Have I been a little bit wet underneath my rain gear before?yes. Was I dry within a half an hour or an hour of being in my tent or under a tarp or while sitting still? yes. When you’re in rain, things are gonna get a little bit wet, but I’ve never been in rain gear that got me so wet that I wasn’t able to get dry quickly with just my body heat. nor has any clients rain gear I've seen.
Just compare the performance of your rain gear to having zero rain gear and you realize that even on its worst day waterproof breathable rain gear is still blocking 95-99% of the water.
In a sustained downpour, you got a manage rain gear, get under a tree for an hour. Let your body heat do some work, drying it out set up a tarp, you can’t just trudge along like you would on a sunny day in pouring down rain and actually expect to be 100% dry.
Also a lot of times you feel wet when you aren’t and sometimes your under layer can wick moisture from the membrane and backer which will have a wet feel to it which is normal.
Just trying to save some guys the trouble of buying a new 700 dollar rain suit when the one they have has the exact same technology and was probably made in the same factory.
My only experience is with 3L rain gear. I have not used any two 2L stuff. None of the hunting companies even have 2L
