Frost butt, while fun to say, is a real danger on the mountain. The fine folks at Helly Hansen are helping combat that frosty foe with the Men's Legendary Pant. The pant is stuffed with 60g PrimaLoft WarmCore in the seat and knees to keep those regions toasty while on long lift rides. To keep snow and moisture out, this pant is made from waterproof, seam sealed Helly Tech Performance 2L mechanical stretch fabric. It's optimized performance with a classic resort look, so you can ski all day, stay protected, and avoid frost butt. Beyond the stretch fabric, to further help you move unhindered, the Legendary offers articulated knees. When you are ripping it on the moguls, you'll probably work up some heat, which you can dump it through the zippered inner thigh vents. Boot gaiters help keep powder out of your boots when you hit a patch of pow, and the reinforced bottom hem keep your skis from slicing your pants open.
