Well I guess my question is what makes this "shell" better than wearing just a normal jacket. I know it has breathability/waterproof ratings. And I read the sticky but am not really sure what it means.
I feel like its saying, if it rains my jacket wont let water get through and I will stay dry. And for breathability if I sweat the excess water leave. But what I don't get it how it will keep me dry. If I sweat, won't it just get soaked in my layers? Obviously the price is what it is because of the ratings, but I guess I just don't fully understand what they do, even after reading the sticky.
