The Houdini Men's Smooth Operator One-Piece Suit lets you head out to ski, ice fish, hike, snowshoe, or camp when winter is at its coldest. Its Polartec Power Stretch Pro provides excellent insulation for the super cold days, and it's also surprisingly soft and supple for how durable it is. Houdini placed its proprietary recycled Econ Stretch fabric in areas that you're most likely to sweat in order to keep you dry, and the breathable microfleece lining also works to wick sweat. The Smooth Operator's slim fit accommodates multiple layers so you'll stay warm whether you're skiing the cold days away or sitting in the middle of an icy lake with a fishing rod, and 3/4-length legs stay out of the way when you're wearing ski or hiking boots. The Smooth Operator's Comfort Cut neckline has a high shaped collar that keeps your neck nice and toasty. There is a full-length zipper at the front and vertical zippers at the lower back for quick bathroom breaks, and the top has a droptail-like construction that prevents you from feeling an uncomfortable breeze while you're doing your business out there. Alpha seams reduce bulk, and articulated sleeves with thumbholes give your arms freedom of movement and keep the sleeves in place.
