If your just sitting on your A$$ and not generating any heat then why do you even need breathable??

When you slip on your Simms garments, with the company logo written all over the outside in big letters, I know you guys feel like superman putting on his cape. What it should say is,
"I just spent a ton of money, pushed against something moist, and now my A$$ is wet.

Waterproof and breathable in the same garment is a sales tactic.
Breathable fabrics leak, don't breath, or do a half A$$ job of each.........Period.
