Update - these aren't the new Savasana camo but the older Wren camo from a couple of years ago and not denim. Sorry to get people excited.
New Wren Camo Wunder Under Pants spotted in stores. They look denim to me. Also shown is the new Post Savasana Pullover ($108). I tried the sweater on today and it's super soft and cozy.
PS - what do you guys think of the denim luon? I finally took the tags off my black camo WUCs yesterday for a step mill workout. I found them on the warm side. The step mill makes me sweat more than running so I am super sensitive to any item that feels "hot."
