What Our Gearhead(R) Experts Are Saying:"I've been rocking the Ninja Suit for years-it's the most comfortable baselayer I've ever owned. The hip zip makes life easy in the backcountry, and the stretchy fabric moves with me no matter what. Once you try it, it's hard to go back to separates."When cold weather hits, we reach for the Classic Ninja Suit-our all-in-one baselayer built to keep us warm and moving freely from first chair to last. With over two decades of refinement, it's dialed for comfort with 230g AIR-TECH stretch fabric that's breathable, cozy, and flexible enough for big tours or deep resort days. The details make it a staple in our kit: a full-length zipper makes it easy to get in and out, thumb loops keep sleeves in place under layers, and the 7-panel fitted hood adds extra warmth when the wind picks up. And yes, the 350deg hip zip means answering nature's call is no problem, even in the middle of a powder day.
