Houdini crafted the Women's Miss H One-Piece Suit with recycled (and recyclable) Eco Circle Alpha and Delta synthetic fabrics. This cozy long-john does more than respect our Earth's resources too: it incorporates warmer Delta panels where you need a bit of extra insulation, and uses lighter material where you want more breathability. A shaped collar, smooth seams, and extra-long sleeves with thumb loops boost comfort even more. And an anti-odor treatment minimizes nasal displeasure on a five-day yurt trip.
