Houdini Airborn Zip
Here's what other sites are saying:
You know how to stay comfortable at the ski resort; all it takes is a protective hardshell, a warm mid-layer, and the Houdini Men's Airborn Zip Top. This baselayer blends merino wool with silk for luxurious comfort that warms you up on chilly chairlifts, cools you down on intense rides, feels incredibly smooth and soft, and yet remains incredibly durable for multiple seasons. It's also naturally antimicrobial, meaning it stays fresh after days of use without a wash. A venting zipper lets out some steam when you work up a sweat. Alpha seams decrease bulk, and thumbholes keep the sleeves in place as well as warm up your palms when the temps drop.
