I LOVE the breathable she carries. I'm actually the one who introduced her to it
The laminate is very soft and stretchy and about as thick as 2 mil non-breathable without the stiffness or plasticky-ness. It wicks just as much or as little as the non-breathable stuff, because the outer fabric is the same. I don't get wicking issues much with any kind of pul, but YMMV.
