I got samples from her and they don't feel all that different to me <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/shrug.gif" style="border:0px solid;" title="shrug"> But I haven't used them.
I LOVE the breathable she carries. I'm actually the one who introduced her to it <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"> 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.
